+
+[section Description and Rationale]
+
+Boost.Algorithm is a collection of general purpose algorithms. While Boost contains many libraries of data structures, there is no single library for general purpose algorithms. Even though the algorithms are generally useful, many tend to be thought of as "too small" for Boost.
+
+An implementation of Boyer-Moore searching, for example, might take a developer a week or so to implement, including test cases and documentation. However, scheduling a review to include that code into Boost might take several months, and run into resistance because "it is too small". Nevertheless, a library of tested, reviewed, documented algorithms can make the developer's life much easier, and that is the purpose of this library.
+
+[heading Future plans]
+
+I will be soliciting submissions from other developers, as well as looking through the literature for existing algorithms to include. The Adobe Source Library, for example, contains many useful algorithms that already have documentation and test cases. Knuth's _The Art of Computer Programming_ is chock-full of algorithm descriptions, too. 
+
+My goal is to run regular algorithm reviews, similar to the Boost library review process, but with smaller chunks of code. 
+
+[heading Dependencies]
+
+Boost.Algorithm uses Boost.Range, Boost.Assert, Boost.Array, Boost.TypeTraits, and Boost.StaticAssert.
+
+
+[heading Acknowledgements]
+
+Thanks to all the people who have reviewed this library and made suggestions for improvements. Steven Watanabe and Sean Parent, in particular, have provided a great deal of help.

+
+
+[heading Overview]
+
+The header file 'boyer_moore.hpp' contains an implementation of the Boyer-Moore algorithm for searching sequences of values. 
+
+The Boyer–Moore string search algorithm is a particularly efficient string searching algorithm, and it has been the standard benchmark for the practical string search literature. The Boyer-Moore algorithm was invented by Bob Boyer and J. Strother Moore, and published in the October 1977 issue of the Communications of the ACM , and a copy of that article is available at [@http://www.cs.utexas.edu/~moore/publications/fstrpos.pdf].
+
+The Boyer-Moore algorithm uses two precomputed tables to give better performance than a naive search. These tables depend on the pattern being searched for, and give the Boyer-Moore algorithm larger a memory footprint and startup costs than a simpler algorithm, but these costs are recovered quickly during the searching process, especially if the pattern is longer than a few elements.
+
+However, the Boyer-Moore algorithm cannot be used with comparison predicates like `std::search`.
+
+Nomenclature: I refer to the sequence being searched for as the "pattern", and the sequence being searched in as the "corpus".
+
+[heading Interface]
+
+For flexibility, the Boyer-Moore algorithm has two interfaces; an object-based interface and a procedural one. The object-based interface builds the tables in the constructor, and uses operator () to perform the search. The procedural interface builds the table and does the search all in one step. If you are going to be searching for the same pattern in multiple corpora, then you should use the object interface, and only build the tables once.
+
+Here is the object interface:
+``
+template <typename patIter>
+class boyer_moore {
+public:
+    boyer_moore ( patIter first, patIter last );
+    ~boyer_moore ();
+    
+    template <typename corpusIter>
+    pair<corpusIter, corpusIter> operator () ( corpusIter corpus_first, corpusIter corpus_last );
+    };
+``
+
+and here is the corresponding procedural interface:
+
+``
+template <typename patIter, typename corpusIter>
+pair<corpusIter, corpusIter> boyer_moore_search ( 
+        corpusIter corpus_first, corpusIter corpus_last, 
+        patIter pat_first, patIter pat_last );
+``
+
+Each of the functions is passed two pairs of iterators. The first two define the corpus and the second two define the pattern. Note that the two pairs need not be of the same type, but they do need to "point" at the same type. In other words, `patIter::value_type` and `curpusIter::value_type` need to be the same type.
+
+The return value of the function is a pair of iterators pointing to the position of the pattern in the corpus. If the pattern is empty, it returns at empty range at the start of the corpus (`corpus_first`, `corpus_first`). If the pattern is not found, it returns at empty range at the end of the corpus (`corpus_last`, `corpus_last`).
+
+[heading Compatibility Note]
+
+Earlier versions of this searcher returned only a single iterator.  As explained in [@https://cplusplusmusings.wordpress.com/2016/02/01/sometimes-you-get-things-wrong/], this was a suboptimal interface choice, and has been changed, starting in the 1.62.0 release.  Old code that is expecting a single iterator return value can be updated by replacing the return value of the searcher's `operator ()` with the `.first` field of the pair.
+
+Instead of:
+``
+iterator foo = searcher(a, b);
+``
+
+you now write:
+``
+iterator foo = searcher(a, b).first;
+``
+
+[heading Performance]
+
+The execution time of the Boyer-Moore algorithm, while still linear in the size of the string being searched, can have a significantly lower constant factor than many other search algorithms: it doesn't need to check every character of the string to be searched, but rather skips over some of them. Generally the algorithm gets faster as the pattern being searched for becomes longer. Its efficiency derives from the fact that with each unsuccessful attempt to find a match between the search string and the text it is searching, it uses the information gained from that attempt to rule out as many positions of the text as possible where the string cannot match.
+
+[heading Memory Use]
+
+The algorithm allocates two internal tables. The first one is proportional to the length of the pattern; the second one has one entry for each member of the "alphabet" in the pattern. For (8-bit) character types, this table contains 256 entries.
+
+[heading Complexity]
+
+The worst-case performance to find a pattern in the corpus is ['O(N)] (linear) time; that is, proportional to the length of the corpus being searched. In general, the search is sub-linear; not every entry in the corpus need be checked.
+
+[heading Exception Safety]
+
+Both the object-oriented and procedural versions of the Boyer-Moore algorithm take their parameters by value and do not use any information other than what is passed in. Therefore, both interfaces provide the strong exception guarantee.
+
+[heading Notes]
+
+* When using the object-based interface, the pattern must remain unchanged for during the searches; i.e, from the time the object is constructed until the final call to operator () returns.
+
+* The Boyer-Moore algorithm requires random-access iterators for both the pattern and the corpus.
+
+[heading Customization points] 
+
+The Boyer-Moore object takes a traits template parameter which enables the caller to customize how one of the precomputed tables is stored. This table, called the skip table, contains (logically) one entry for every possible value that the pattern can contain. When searching 8-bit character data, this table contains 256 elements. The traits class defines the table to be used. 
+
+The default traits class uses a `boost::array` for small 'alphabets' and a `tr1::unordered_map` for larger ones.  The array-based skip table gives excellent performance, but could be prohibitively large when the 'alphabet' of elements to be searched grows. The unordered_map based version only grows as the number of unique elements in the pattern, but makes many more heap allocations, and gives slower lookup performance. 
+
+To use a different skip table, you should define your own skip table object and your own traits class, and use them to instantiate the Boyer-Moore object. The interface to these objects is described TBD.

+
+[heading Overview]
+
+The header file 'boyer_moore_horspool.hpp' contains an implementation of the Boyer-Moore-Horspool algorithm for searching sequences of values. 
+
+The Boyer-Moore-Horspool search algorithm was published by Nigel Horspool in 1980. It is a refinement of the Boyer-Moore algorithm that trades space for time. It uses less space for internal tables than Boyer-Moore, and has poorer worst-case performance.
+
+The Boyer-Moore-Horspool algorithm cannot be used with comparison predicates like `std::search`.
+
+[heading Interface]
+
+Nomenclature: I refer to the sequence being searched for as the "pattern", and the sequence being searched in as the "corpus".
+
+For flexibility, the Boyer-Moore-Horspool algorithm has two interfaces; an object-based interface and a procedural one. The object-based interface builds the tables in the constructor, and uses operator () to perform the search. The procedural interface builds the table and does the search all in one step. If you are going to be searching for the same pattern in multiple corpora, then you should use the object interface, and only build the tables once.
+
+Here is the object interface:
+``
+template <typename patIter>
+class boyer_moore_horspool {
+public:
+    boyer_moore_horspool ( patIter first, patIter last );
+    ~boyer_moore_horspool ();
+    
+    template <typename corpusIter>
+    pair<corpusIter, corpusIter> operator () ( corpusIter corpus_first, corpusIter corpus_last );
+    };
+``
+
+and here is the corresponding procedural interface:
+
+``
+template <typename patIter, typename corpusIter>
+pair<corpusIter, corpusIter> boyer_moore_horspool_search ( 
+        corpusIter corpus_first, corpusIter corpus_last, 
+        patIter pat_first, patIter pat_last );
+``
+
+Each of the functions is passed two pairs of iterators. The first two define the corpus and the second two define the pattern. Note that the two pairs need not be of the same type, but they do need to "point" at the same type. In other words, `patIter::value_type` and `curpusIter::value_type` need to be the same type.
+
+The return value of the function is a pair of iterators pointing to the position of the pattern in the corpus. If the pattern is empty, it returns at empty range at the start of the corpus (`corpus_first`, `corpus_first`). If the pattern is not found, it returns at empty range at the end of the corpus (`corpus_last`, `corpus_last`).
+
+[heading Compatibility Note]
+
+Earlier versions of this searcher returned only a single iterator.  As explained in [@https://cplusplusmusings.wordpress.com/2016/02/01/sometimes-you-get-things-wrong/], this was a suboptimal interface choice, and has been changed, starting in the 1.62.0 release.  Old code that is expecting a single iterator return value can be updated by replacing the return value of the searcher's `operator ()` with the `.first` field of the pair.
+
+Instead of:
+``
+iterator foo = searcher(a, b);
+``
+
+you now write:
+``
+iterator foo = searcher(a, b).first;
+``
+
+[heading Performance]
+
+The execution time of the Boyer-Moore-Horspool algorithm is linear in the size of the string being searched; it can have a significantly lower constant factor than many other search algorithms: it doesn't need to check every character of the string to be searched, but rather skips over some of them. Generally the algorithm gets faster as the pattern being searched for becomes longer. Its efficiency derives from the fact that with each unsuccessful attempt to find a match between the search string and the text it is searching, it uses the information gained from that attempt to rule out as many positions of the text as possible where the string cannot match.
+
+[heading Memory Use]
+
+The algorithm an internal table that has one entry for each member of the "alphabet" in the pattern. For (8-bit) character types, this table contains 256 entries.
+
+[heading Complexity]
+
+The worst-case performance is ['O(m x n)], where ['m] is the length of the pattern and ['n] is the length of the corpus. The average time is ['O(n)]. The best case performance is sub-linear, and is, in fact, identical to Boyer-Moore, but the initialization is quicker and the internal loop is simpler than Boyer-Moore.
+
+[heading Exception Safety]
+
+Both the object-oriented and procedural versions of the Boyer-Moore-Horspool algorithm take their parameters by value and do not use any information other than what is passed in. Therefore, both interfaces provide the strong exception guarantee.
+
+[heading Notes]
+
+* When using the object-based interface, the pattern must remain unchanged for during the searches; i.e, from the time the object is constructed until the final call to operator () returns.
+
+* The Boyer-Moore-Horspool algorithm requires random-access iterators for both the pattern and the corpus.
+
+[heading Customization points] 
+
+The Boyer-Moore-Horspool object takes a traits template parameter which enables the caller to customize how the precomputed table is stored. This table, called the skip table, contains (logically) one entry for every possible value that the pattern can contain. When searching 8-bit character data, this table contains 256 elements. The traits class defines the table to be used. 
+
+The default traits class uses a `boost::array` for small 'alphabets' and a `tr1::unordered_map` for larger ones.  The array-based skip table gives excellent performance, but could be prohibitively large when the 'alphabet' of elements to be searched grows. The unordered_map based version only grows as the number of unique elements in the pattern, but makes many more heap allocations, and gives slower lookup performance. 
+
+To use a different skip table, you should define your own skip table object and your own traits class, and use them to instantiate the Boyer-Moore-Horspool object. The interface to these objects is described TBD.

+The header file clamp.hpp contains two functions for "clamping" a value between a pair of boundary values.
+
+[heading clamp]
+
+The function `clamp (v, lo, hi)` returns:
+
+* lo if v < lo
+* hi if hi < v
+* otherwise, v
+
+Note: using `clamp` with floating point numbers may give unexpected results if one of the values is `NaN`.
+
+There is also a version that allows the caller to specify a comparison predicate to use instead of `operator <`.
+
+``
+template<typename T> 
+const T& clamp ( const T& val, const T& lo, const T& hi );
+
+template<typename T, typename Pred> 
+const T& clamp ( const T& val, const T& lo, const T& hi, Pred p );
+``
+
+The following code: ``
+   int foo = 23;
+   foo = clamp ( foo, 1, 10 );
+``
+will leave `foo` with a value of 10
+
+Complexity:
+	`clamp` will make either one or two calls to the comparison predicate before returning one of the three parameters.
+
+[heading clamp_range]
+There are also four range-based versions of clamp, that apply clamping to a series of values. You could write them yourself with std::transform and bind, like this: `std::transform ( first, last, out, bind ( clamp ( _1, lo, hi )))`, but they are provided here for your convenience.

+
+The header file 'equal.hpp' contains two variants of a the stl algorithm `equal`. The algorithm tests to see if two sequences contain equal values;  
+
+Before (the proposed) C++14 the algorithm `std::equal` took three iterators and an optional comparison predicate. The first two iterators `[first1, last1)` defined a sequence, and the second one `first2` defined the start of the second sequence. The second sequence was assumed to be the same length as the first. 
+
+In C++14, two new variants were introduced, taking four iterators and an optional comparison predicate. The four iterators define two sequences `[first1, last1)` and `[first2, last2)` explicitly, rather than defining the second one implicitly. This leads to correct answers in more cases (and avoid undefined behavior in others).
+
+Consider the two sequences:
+```
+	auto seq1 = { 0, 1, 2 };
+	auto seq2 = { 0, 1, 2, 3, 4 };
+	
+	std::equal ( seq1.begin (), seq1.end (), seq2.begin ()); // true
+	std::equal ( seq2.begin (), seq2.end (), seq1.begin ()); // Undefined behavior
+	std::equal ( seq1.begin (), seq1.end (), seq2.begin (), seq2.end ()); // false
+```
+
+You can argue that `true` is the correct answer in the first case, even though the sequences are not the same. The first N entries in `seq2` are the same as the entries in `seq1` - but that's not all that's in `seq2`. But in the second case, the algorithm will read past the end of `seq1`, resulting in undefined behavior (large earthquake, incorrect results, pregnant cat, etc).
+
+However, if the two sequences are specified completely, it's clear that they are not equal.
+
+[heading interface]
+
+The function `equal` returns true if the two sequences compare equal; i.e, if each element in the sequence compares equal to the corresponding element in the other sequence. One version uses `std::equal_to` to do the comparison; the other lets the caller pass predicate to do the comparisons. 
+
+``
+template <class InputIterator1, class InputIterator2>
+bool equal ( InputIterator1 first1, InputIterator1 last1, 
+             InputIterator2 first2, InputIterator2 last2 );
+             
+template <class InputIterator1, class InputIterator2, class BinaryPredicate>
+bool equal ( InputIterator1 first1, InputIterator1 last1, 
+             InputIterator2 first2, InputIterator2 last2, BinaryPredicate pred );
+``
+
+[heading Examples]
+
+Given the container `c1` containing `{ 0, 1, 2, 3, 14, 15 }`, and `c2` containing `{ 1, 2, 3 }`,  then
+``
+equal ( c1.begin (),     c1.end (),       c2.begin (), c2.end ()) --> false
+equal ( c1.begin () + 1, c1.begin () + 3, c2.begin (), c2.end ()) --> true
+equal ( c1.end (),       c1.end (),       c2.end (),   c2.end ()) --> true  // empty sequences are alway equal to each other
+``
+
+[heading Iterator Requirements]
+
+`equal` works on all iterators except output iterators.
+
+[heading Complexity]
+
+Both of the variants of `equal` run in ['O(N)] (linear) time; that is, they compare against each element in the list once. If the sequence is found to be not equal at any point, the routine will terminate immediately, without examining the rest of the elements.
+
+[heading Exception Safety]
+
+Both of the variants of `equal` take their parameters by value and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
+
+[heading Notes]
+
+* The four iterator version of the routine `equal` is part of the C++14 standard. When C++14 standard library implementations become available, the implementation from the standard library should be used.
+
+* `equal` returns true for two empty ranges, no matter what predicate is passed to test against.

+
+The header file 'find_backward.hpp' contains variants of the stl algorithm
+`find`. These variants are like `find`, except that the evaluate the elements
+of the given sequence in reverse order.
+
+Consider how finding the last element that is equal to `x` in a range is
+typically done:
+
+    // Assume a valid range if elements delimited by [first, last).
+    while (last-- != first) {
+        if (*last == x) {
+            // Use last here...
+        }
+    }
+
+Raw loops are icky though.  Perhaps we should do a bit of extra work to allow
+the use of `std::find()`:
+
+    auto rfirst = std::make_reverse_iterator(last);
+    auto rlast = std::make_reverse_iterator(first);
+    auto it = std::find(rfirst, rlast, x);
+    // Use it here...
+
+That seems nicer in that there is no raw loop, but it has two major drawbacks.
+First, it requires an unpleasant amount of typing.  Second, it is less
+efficient than forward-iterator `find` , since `std::reverse_iterator` calls
+its base-iterator's `operator--()` in most of its member functions before
+doing the work that the member function requires.

+The header file 'find_not.hpp' contains a variants of a the stl algorithm

+Consider this use of `find()`:
+
+    std::vector<int> vec = { 1, 1, 2 };
+    auto it = std::find(vec.begin(), vec.end(), 1);
+
+This gives us the first occurance of `1` in `vec`.  What if we want to find

+

+The header file 'boost/algorithm/gather.hpp' contains two variants of a single algorithm, `gather`. 
+
+`gather()` takes a collection of elements defined by a pair of iterators and moves the ones satisfying a predicate to them to a position (called the pivot) within the sequence. The algorithm is stable. The result is a pair of iterators that contains the items that satisfy the predicate.
+
+[heading Interface]
+
+The function `gather` returns a `std::pair` of iterators that denote the elements that satisfy the predicate.  
+
+There are two versions; one takes two iterators, and the other takes a range.

+  first |  second
+      pivot
+``
+where `first` and `second` are the fields of the pair that is returned by the call.
+
+
+[heading Iterator Requirements]
+
+`gather` work on bidirectional iterators or better. This requirement comes from the usage of `stable_partition`, which requires bidirectional iterators. Some standard libraries (libstdc++ and libc++, for example) have implementations of `stable_partition` that work with forward iterators. If that is the case, then `gather` will work with forward iterators as well.
+
+[heading Storage Requirements]
+
+`gather` uses `stable_partition`, which will attempt to allocate temporary memory, but will work in-situ if there is none available.
+
+[heading Complexity]
+
+If there is sufficient memory available, the run time is linear: `O(N)`
+
+If there is not any memory available, then the run time is `O(N log N)`.

+The first one takes an iterator pair. The second one takes a pointer to the start of a zero-terminated sequence, such as a c string, and the third takes a range as defined by the Boost.Range library.
+
+``
+template <typename InputIterator, typename OutputIterator>
+OutputIterator hex ( InputIterator first, InputIterator last, OutputIterator out );
+
+template <typename T, typename OutputIterator>
+OutputIterator hex ( const T *ptr, OutputIterator out );
+
+template <typename Range, typename OutputIterator>
+OutputIterator hex ( const Range &r, OutputIterator out );
+``
+
+`hex` writes only values in the range '0'..'9' and 'A'..'F', but is not limited to character output. The output iterator could refer to a wstring, or a vector of integers, or any other integral type.
+
+The function `unhex` takes the output of `hex` and turns it back into a sequence of values.
+
+The input parameters for the different variations of `unhex` are the same as `hex`.
+
+``
+template <typename InputIterator, typename OutputIterator>
+OutputIterator unhex ( InputIterator first, InputIterator last, OutputIterator out );
+
+template <typename T, typename OutputIterator>
+OutputIterator unhex ( const T *ptr, OutputIterator out );
+
+template <typename Range, typename OutputIterator>
+OutputIterator unhex ( const Range &r, OutputIterator out );
+``
+
+[heading Error Handling]
+The header 'hex.hpp' defines three exception classes:
+``
+struct hex_decode_error: virtual boost::exception, virtual std::exception {};
+struct not_enough_input : public hex_decode_error;
+struct non_hex_input : public hex_decode_error;
+``
+
+If the input to `unhex` does not contain an "even number" of hex digits, then an exception of type `boost::algorithm::not_enough_input` is thrown.
+
+If the input to `unhex` contains any non-hexadecimal characters, then an exception of type `boost::algorithm::non_hex_input` is thrown.
+
+If you want to catch all the decoding errors, you can catch exceptions of type `boost::algorithm::hex_decode_error`.
+
+[heading Examples]
+
+Assuming that `out` is an iterator that accepts `char` values, and `wout` accepts `wchar_t` values (and that sizeof ( wchar_t ) == 2)
+
+``
+hex ( "abcdef", out )  --> "616263646566"
+hex ( "32", out )     --> "3332"
+hex ( "abcdef", wout ) --> "006100620063006400650066"
+hex ( "32", wout )    --> "00330032"
+
+unhex ( "616263646566", out )  --> "abcdef"
+unhex ( "3332", out )          --> "32"
+unhex ( "616263646566", wout ) --> "\6162\6364\6566"	( i.e, a 3 character string )
+unhex ( "3332", wout )         --> "\3233"				( U+3332, SQUARE HUARADDO )
+
+unhex ( "3", out )            --> Error - not enough input
+unhex ( "32", wout )          --> Error - not enough input
+
+unhex ( "ACEG", out )         --> Error - non-hex input
+
+``
+
+[heading Iterator Requirements]
+
+`hex` and `unhex` work on all iterator types.
+
+[heading Complexity]
+
+All of the variants of `hex` and `unhex` run in ['O(N)] (linear) time; that is, that is, they process each element in the input sequence once.
+
+[heading Exception Safety]
+
+All of the variants of `hex` and `unhex` take their parameters by value or const reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee. However, when working on input iterators, if an exception is thrown, the input iterators will not be reset to their original values (i.e, the characters read from the iterator cannot be un-read)
+
+[heading Notes]
+
+* `hex` and `unhex` both do nothing when passed empty ranges.

+
+Distributed under the Boost Software License, Version 1.0.
+(See accompanying file LICENSE_1_0.txt or copy at
+http://www.boost.org/LICENSE_1_0.txt)
+]
+
+
+[heading Overview]
+
+The header file 'knuth_morris_pratt.hpp' contains an implementation of the Knuth-Morris-Pratt algorithm for searching sequences of values. 
+
+The basic premise of the Knuth-Morris-Pratt algorithm is that when a mismatch occurs, there is information in the pattern being searched for that can be used to determine where the next match could begin, enabling the skipping of some elements of the corpus that have already been examined.
+
+It does this by building a table from the pattern being searched for, with one entry for each element in the pattern.
+
+The algorithm was conceived in 1974 by Donald Knuth and Vaughan Pratt, and independently by James H. Morris. The three published it jointly in 1977 in the SIAM Journal on Computing [@http://citeseer.ist.psu.edu/context/23820/0]
+
+However, the Knuth-Morris-Pratt algorithm cannot be used with comparison predicates like `std::search`.
+
+[heading Interface]
+
+Nomenclature: I refer to the sequence being searched for as the "pattern", and the sequence being searched in as the "corpus".
+
+For flexibility, the Knuth-Morris-Pratt algorithm has two interfaces; an object-based interface and a procedural one. The object-based interface builds the table in the constructor, and uses operator () to perform the search. The procedural interface builds the table and does the search all in one step. If you are going to be searching for the same pattern in multiple corpora, then you should use the object interface, and only build the tables once.
+
+Here is the object interface:
+``
+template <typename patIter>
+class knuth_morris_pratt {
+public:
+    knuth_morris_pratt ( patIter first, patIter last );
+    ~knuth_morris_pratt ();
+    
+    template <typename corpusIter>
+    pair<corpusIter, corpusIter> operator () ( corpusIter corpus_first, corpusIter corpus_last );
+    };
+``
+
+and here is the corresponding procedural interface:
+
+``
+template <typename patIter, typename corpusIter>
+pair<corpusIter, corpusIter> knuth_morris_pratt_search ( 
+        corpusIter corpus_first, corpusIter corpus_last, 
+        patIter pat_first, patIter pat_last );
+``
+
+Each of the functions is passed two pairs of iterators. The first two define the corpus and the second two define the pattern. Note that the two pairs need not be of the same type, but they do need to "point" at the same type. In other words, `patIter::value_type` and `curpusIter::value_type` need to be the same type.
+
+The return value of the function is a pair of iterators pointing to the position of the pattern in the corpus. If the pattern is empty, it returns at empty range at the start of the corpus (`corpus_first`, `corpus_first`). If the pattern is not found, it returns at empty range at the end of the corpus (`corpus_last`, `corpus_last`).
+
+[heading Compatibility Note]
+
+Earlier versions of this searcher returned only a single iterator.  As explained in [@https://cplusplusmusings.wordpress.com/2016/02/01/sometimes-you-get-things-wrong/], this was a suboptimal interface choice, and has been changed, starting in the 1.62.0 release.  Old code that is expecting a single iterator return value can be updated by replacing the return value of the searcher's `operator ()` with the `.first` field of the pair.
+
+Instead of:
+``
+iterator foo = searcher(a, b);
+``
+
+you now write:
+``
+iterator foo = searcher(a, b).first;
+``
+[heading Performance]
+
+The execution time of the Knuth-Morris-Pratt algorithm is linear in the size of the string being searched. Generally the algorithm gets faster as the pattern being searched for becomes longer. Its efficiency derives from the fact that with each unsuccessful attempt to find a match between the search string and the text it is searching, it uses the information gained from that attempt to rule out as many positions of the text as possible where the string cannot match.
+
+[heading Memory Use]
+
+The algorithm an that contains one entry for each element the pattern, plus one extra.  So, when searching for a 1026 byte string, the table will have 1027 entries.
+
+[heading Complexity]
+
+The worst-case performance is ['O(2n)], where ['n] is the length of the corpus. The average time is ['O(n)]. The best case performance is sub-linear.
+
+[heading Exception Safety]
+
+Both the object-oriented and procedural versions of the Knuth-Morris-Pratt algorithm take their parameters by value and do not use any information other than what is passed in. Therefore, both interfaces provide the strong exception guarantee.
+
+[heading Notes]
+
+* When using the object-based interface, the pattern must remain unchanged for during the searches; i.e, from the time the object is constructed until the final call to operator () returns.
+
+* The Knuth-Morris-Pratt algorithm requires random-access iterators for both the pattern and the corpus. It should be possible to write this to use bidirectional iterators (or possibly even forward ones), but this implementation does not do that.

+
+The header file 'mismatch.hpp' contains two variants of a the stl algorithm `mismatch`. The algorithm finds the first point in two sequences where they do not match.
+
+Before (the proposed) C++14 the algorithm `std::mismatch` took three iterators and an optional comparison predicate. The first two iterators `[first1, last1)` defined a sequence, and the second one `first2` defined the start of the second sequence. The second sequence was assumed to be the same length as the first. 
+
+In C++14, two new variants were introduced, taking four iterators and an optional comparison predicate. The four iterators define two sequences `[first1, last1)` and `[first2, last2)` explicitly, rather than defining the second one implicitly. This leads to correct answers in more cases (and avoid undefined behavior in others).
+
+Consider the two sequences:
+```
+	auto seq1 = { 0, 1, 2 };
+	auto seq2 = { 0, 1, 2, 3, 4 };
+	
+	std::mismatch ( seq1.begin (), seq1.end (), seq2.begin ()); // <3, 3>
+	std::mismatch ( seq2.begin (), seq2.end (), seq1.begin ()); // Undefined behavior
+	std::mismatch ( seq1.begin (), seq1.end (), seq2.begin (), seq2.end ()); // <3, 3>
+```
+
+The first N entries in `seq2` are the same as the entries in `seq1` - but that's not all that's in `seq2`. In the second case, the algorithm will read past the end of `seq1`, resulting in undefined behavior (large earthquake, incorrect results, pregnant cat, etc).
+
+However, if the two sequences are specified completely, it's clear that where the mismatch occurs.
+
+[heading interface]
+
+The function `mismatch` returns a pair of iterators which denote the first mismatching elements in each sequence. If the sequences match completely, `mismatch` returns their end iterators. One version uses `std::equal_to` to do the comparison; the other lets the caller pass predicate to do the comparisons. 
+
+``
+template <class InputIterator1, class InputIterator2>
+std::pair<InputIterator1, InputIterator2>
+mismatch ( InputIterator1 first1, InputIterator1 last1, 
+           InputIterator2 first2, InputIterator2 last2 );
+             
+template <class InputIterator1, class InputIterator2, class BinaryPredicate>
+std::pair<InputIterator1, InputIterator2>
+mismatch ( InputIterator1 first1, InputIterator1 last1, 
+           InputIterator2 first2, InputIterator2 last2, BinaryPredicate pred );
+``
+
+[heading Examples]
+
+Given the container `c1` containing `{ 0, 1, 2, 3, 14, 15 }`, and `c2` containing `{ 1, 2, 3 }`,  then
+``
+mismatch ( c1.begin(),     c1.end(),       c2.begin(), c2.end()) --> <c1.begin(), c2.begin()> // first elements do not match
+mismatch ( c1.begin() + 1, c1.begin() + 4, c2.begin(), c2.end()) --> <c1.begin() + 4, c2.end ()> // all elements of `c2` match
+mismatch ( c1.end(),       c1.end(),       c2.end(),   c2.end()) --> <c1.end(), c2.end()> // empty sequences don't match at the end.
+``
+
+[heading Iterator Requirements]
+
+`mismatch` works on all iterators except output iterators.
+
+[heading Complexity]
+
+Both of the variants of `mismatch` run in ['O(N)] (linear) time; that is, they compare against each element in the list once. If the sequence is found to be not equal at any point, the routine will terminate immediately, without examining the rest of the elements.
+
+[heading Exception Safety]
+
+Both of the variants of `mismatch` take their parameters by value and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
+
+[heading Notes]
+
+* If the sequences are equal (or both are empty), then mismatch returns the end iterators of both sequences. 
+
+* The four iterator version of the routine `mismatch` is part of the C++14 standard. When C++14 standard library implementations become available, the implementation from the standard library should be used.

+
+The header file `<boost/algorithm/cxx11/is_sorted.hpp>` contains functions for determining if a sequence is ordered.
+
+[heading is_sorted]
+The function `is_sorted(sequence)` determines whether or not a sequence is completely sorted according so some criteria.  If no comparison predicate is specified, then `std::less` is used (i.e, the test is to see if the sequence is non-decreasing)
+
+``
+namespace boost { namespace algorithm {
+	template <typename ForwardIterator, typename Pred>
+	bool is_sorted ( ForwardIterator first, ForwardIterator last, Pred p );
+	
+	template <typename ForwardIterator>
+	bool is_sorted ( ForwardIterator first, ForwardIterator last );
+	
+	
+	template <typename Range, typename Pred>
+	bool is_sorted ( const Range &r, Pred p );
+	
+	template <typename Range>
+	bool is_sorted ( const Range &r );
+}}
+``
+
+Iterator requirements: The `is_sorted` functions will work forward iterators or better.
+
+[heading is_sorted_until]
+
+If `distance(first, last) < 2`, then `is_sorted ( first, last )` returns `last`. Otherwise, it returns the last iterator i in [first,last] for which the range [first,i) is sorted.
+
+In short, it returns the element in the sequence that is "out of order". If the entire sequence is sorted (according to the predicate), then it will return `last`.
+
+``
+namespace boost { namespace algorithm {
+	template <typename ForwardIterator, typename Pred>
+	FI is_sorted_until ( ForwardIterator first, ForwardIterator last, Pred p );
+	
+	template <typename ForwardIterator>
+	ForwardIterator is_sorted_until ( ForwardIterator first, ForwardIterator last );
+	
+	
+	template <typename Range, typename Pred>
+	typename boost::range_iterator<const R>::type is_sorted_until ( const Range &r, Pred p );
+	
+	template <typename Range>
+	typename boost::range_iterator<const R>::type is_sorted_until ( const Range &r );
+}}
+``
+
+Iterator requirements: The `is_sorted_until` functions will work on forward iterators or better. Since they have to return a place in the input sequence, input iterators will not suffice.
+
+Complexity:
+	`is_sorted_until` will make at most ['N-1] calls to the predicate (given a sequence of length ['N]).
+
+Examples:
+
+Given the sequence `{ 1, 2, 3, 4, 5, 3 }`,   `is_sorted_until ( beg, end, std::less<int>())` would return an iterator pointing at the second `3`.
+
+Given the sequence `{ 1, 2, 3, 4, 5, 9 }`,   `is_sorted_until ( beg, end, std::less<int>())` would return `end`.
+
+
+There are also a set of "wrapper functions" for is_ordered which make it easy to see if an entire sequence is ordered. These functions return a boolean indicating success or failure rather than an iterator to where the out of order items were found.
+
+To test if a sequence is increasing (each element at least as large as the preceding one):
+``
+namespace boost { namespace algorithm {
+	template <typename Iterator>
+	bool is_increasing ( Iterator first, Iterator last );
+	
+	template <typename R>
+	bool is_increasing ( const R &range );
+}}
+``
+
+To test if a sequence is decreasing (each element no larger than the preceding one):
+
+``
+namespace boost { namespace algorithm {
+	template <typename ForwardIterator>
+	bool is_decreasing ( ForwardIterator first, ForwardIterator last );
+	
+	template <typename R>
+	bool is_decreasing ( const R &range );
+}}
+``
+
+To test if a sequence is strictly increasing (each element larger than the preceding one):
+``
+namespace boost { namespace algorithm {
+	template <typename ForwardIterator>
+	bool is_strictly_increasing ( ForwardIterator first, ForwardIterator last );
+	
+	template <typename R>
+	bool is_strictly_increasing ( const R &range );
+}}
+``
+
+To test if a sequence is strictly decreasing (each element smaller than the preceding one):
+``
+namespace boost { namespace algorithm {
+	template <typename ForwardIterator>
+	bool is_strictly_decreasing ( ForwardIterator first, ForwardIterator last );
+	
+	template <typename R>
+	bool is_strictly_decreasing ( const R &range );
+}}
+``
+
+Complexity:
+	Each of these calls is just a thin wrapper over `is_sorted`, so they have the same complexity as `is_sorted`.
+
+[heading Notes]
+
+* The routines `is_sorted` and `is_sorted_until` are part of the C++11 standard. When compiled using a C++11 implementation, the implementation from the standard library will be used.

+    \defgroup gather gather
+    \ingroup mutating_algorithm
+
+    \c gather() takes a collection of elements defined by a pair of iterators and moves
+    the ones satisfying a predicate to them to a position (called the pivot) within
+    the sequence. The algorithm is stable. The result is a pair of iterators that
+    contains the items that satisfy the predicate.
+
+    Given an sequence containing:
+    <pre>
+    0 1 2 3 4 5 6 7 8 9
+    </pre>
+
+    a call to gather ( arr, arr + 10, arr + 4, IsEven ()) will result in:
+
+    <pre>
+    1 3 0 2 4 6 8 5 7 9
+        |---|-----|
+      first |  second
+          pivot
+    </pre>
+
+
+    The problem is broken down into two basic steps, namely, moving the items before the pivot
+    and then moving the items from the pivot to the end. These "moves" are done with calls to
+    stable_partition.
+
+    \par Storage Requirements:
+
+    The algorithm uses stable_partition, which will attempt to allocate temporary memory,
+    but will work in-situ if there is none available.
+
+    \par Time Complexity:
+
+    If there is sufficient memory available, the run time is linear in <code>N</code>.
+    If there is not any memory available, then the run time is <code>O(N log N)</code>.

+
+The Boyer-Moore search algorithm uses two tables, a "bad character" table
+to tell how far to skip ahead when it hits a character that is not in the pattern,
+and a "good character" table to tell how far to skip ahead when it hits a
+mismatch on a character that _is_ in the pattern.
+
+Requirements:
+        * Random access iterators
+        * The two iterator types (patIter and corpusIter) must 
+            "point to" the same underlying type and be comparable.
+        * Additional requirements may be imposed but the skip table, such as:
+        ** Numeric type (array-based skip table)
+        ** Hashable type (map-based skip table)
