+# Generic Travis CI build script for boostorg repositories
+# See: https://github.com/boostorg/boost-ci
+#
+# Instructions for customizing this script for your library:
+#
+# 1. Customize the compilers and language levels you want in the 'jobs'.
+# 2. If you have more than include/, src/, test/, example/, examples/, or
+#    tools/ directories, modify your Travis CI project and add the environment
+#    variable DEPINST.  For example if your build uses code in "bench/" and
+#    "fog/" directories, then set DEPINST to the following:
+#        --include bench --include fog
+# 3. If you want to enable Coverity Scan, you need to provide the environment
+#    variables COVERITY_SCAN_TOKEN and COVERITY_SCAN_NOTIFICATION_EMAIL in
+#    your github settings.
+# 4. Enable pull request builds in your boostorg/<library> account.
+#
+# That's it - the scripts will do everything else for you.

+
+The header file [^[link header.boost.algorithm.apply_permutation_hpp apply_permutation.hpp]] contains two algorithms, `apply_permutation` and `apply_reverse_permutation`. There are also range-based versions.
+The algorithms transform the item sequence according to index sequence order.
+
+The routine `apply_permutation` takes a item sequence and a order sequence. It reshuffles item sequence according to order sequence. Every value in order sequence means where the item comes from. Order sequence needs to be exactly a permutation of the sequence [0, 1, ... , N], where N is the biggest index in the item sequence (zero-indexed).
+The routine `apply_reverse_permutation` takes a item sequence and a order sequence. It will reshuffle item sequence according to order sequence. Every value in order sequence means where the item goes to. Order sequence needs to be exactly a permutation of the sequence [0, 1, ... , N], where N is the biggest index in the item sequence (zero-indexed).

+
+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. 
+
+``

+
+`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.

+
+Consider how finding the last element that is equal to `x` in a range is

+        if (*last == x) {
+            // Use last here...

+Raw loops are icky though.  Perhaps we should do a bit of extra work to allow

+
+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

+
+This gives us the first occurance of `1` in `vec`.  What if we want to find

+The header file 'is_palindrome.hpp' contains six variants of a single algorithm, is_palindrome. 
+The algorithm tests the sequence and returns true if the sequence is a palindrome; i.e, it is identical when traversed either backwards or frontwards.

+
+The routine come in 6 forms; the first one takes two iterators to define the range. The second form takes two iterators to define the range and a predicate. 
+The third form takes a single range parameter, and uses Boost.Range to traverse it. The fourth form takes a single range parameter ( uses Boost.Range to traverse it) and a predicate.

 [heading Overview]
 
-The header file 'knuth_morris_pratt.hpp' contains an an implementation of the Knuth-Morris-Pratt algorithm for searching sequences of values. 
+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>

+
+    \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>.
