+# 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.

+
+* [Ask questions](http://stackoverflow.com/questions/ask?tags=c%2B%2B,boost,boost-algorithm)
+* [Report bugs](https://github.com/boostorg/algorithm/issues): Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
+* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](http://www.boost.org/LICENSE_1_0.txt).
+* Discussions about the library are held on the [Boost developers mailing list](http://www.boost.org/community/groups.html#main). Be sure to read the [discussion policy](http://www.boost.org/community/policy.html) before posting and add the `[algorithm]` tag at the beginning of the subject line.

+# See: https://github.com/boostorg/boost-ci/
+#
+# Instructions for customizing this script for your library:
+#
+# 1. Customize the compilers and language levels you want.
+# 2. If you have more than include/, src/, test/, example/, examples/,
+#    benchmark/ or tools/ directories, set the environment variable DEPINST.
+#    For example if your build uses code in "bench/" and "fog/" directories:
+#      - DEPINST: --include bench --include fog
+# 3. Enable pull request builds in your boostorg/<library> account.
+#
+# That's it - the script 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).

 Consider this use of `find()`:

     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 first occurrance of any number besides `1` in `vec`?  We have to write an
 unfortunate amount of code:
 
-    auto std::vector<int> vec = { 1, 1, 2 };
+    std::vector<int> vec = { 1, 1, 2 };
     auto it = std::find_if(vec.begin(), vec.end(), [](int i) { return i != 1; });
 
 With `find_not()` the code gets much more terse:

+    std::vector<int> vec = { 1, 1, 2 };
     auto it = find_not(vec.begin(), vec.end(), 1);

+
+There are times that you want a sorted version of a sequence, but for some reason you don't want to modify it.  Maybe the elements in the sequence can't be moved/copied, e.g. the sequence is const, or they're just really expensive to move around.   An example of this might be a sequence of records from a database.
+
+That's where indirect sorting comes in.  In a "normal" sort, the elements of the sequence to be sorted are shuffled in place.  In indirect sorting, the elements are unchanged, but the sort algorithm returns a "permutation" of the elements that, when applied, will put the elements in the sequence in a sorted order.
+
+Assume have a sequence `[first, last)` of 1000 items that are expensive to swap:
+```
+	std::sort(first, last);  // ['O(N ln N)] comparisons and ['O(N ln N)] swaps (of the element type).
+```
+
+On the other hand, using indirect sorting:
+```
+	auto perm = indirect_sort(first, last);  // ['O(N lg N)] comparisons and ['O(N lg N)] swaps (of size_t).
+	apply_permutation(first, last, perm.begin(), perm.end()); // ['O(N)] swaps (of the element type)
+```
+
+If the element type is sufficiently expensive to swap, then 10,000 swaps of size_t + 1000 swaps of the element_type could be cheaper than 10,000 swaps of the element_type.
+
+Or maybe you don't need the elements to actually be sorted - you just want to traverse them in a sorted order:
+```
+	auto permutation = indirect_sort(first, last);
+	for (size_t idx: permutation)
+		std::cout << first[idx] << std::endl;
+```
+
+
+Assume that instead of an "array of structures", you have a "struct of arrays".
+```
+struct AType {
+	Type0 key;
+	Type1 value1;
+	Type1 value2;
+	};
+
+std::array<AType, 1000> arrayOfStruct;
+```
+
+versus:
+
+```
+template <size_t N>
+struct AType {
+	std::array<Type0, N> key;
+	std::array<Type1, N> value1;
+	std::array<Type2, N> value2;
+	};
+	
+AType<1000> structOfArrays;
+```
+
+Sorting the first one is easy, because each set of fields (`key`, `value1`, `value2`) are part of the same struct.  But with indirect sorting, the second one is easy to sort as well - just sort the keys, then apply the permutation to the keys and the values:
+```
+	auto perm = indirect_sort(std::begin(structOfArrays.key), std::end(structOfArrays.key));
+	apply_permutation(structOfArrays.key.begin(),    structOfArrays.key.end(),    perm.begin(), perm.end());
+	apply_permutation(structOfArrays.value1.begin(), structOfArrays.value1.end(), perm.begin(), perm.end());
+	apply_permutation(structOfArrays.value2.begin(), structOfArrays.value2.end(), perm.begin(), perm.end());
+```
+
+[heading interface]
+
+The function `indirect_sort` returns a `vector<size_t>` containing the permutation necessary to put the input sequence into a sorted order. One version uses `std::less` to do the comparisons; the other lets the caller pass predicate to do the comparisons. 
+
+There is also a variant called `indirect_stable_sort`; it bears the same relation to `indirect_sort` that `std::stable_sort` does to `std::sort`.
+
+```
+template <typename RAIterator>
+std::vector<size_t> indirect_sort (RAIterator first, RAIterator last);
+
+template <typename RAIterator, typename BinaryPredicate>
+std::vector<size_t> indirect_sort (RAIterator first, RAIterator last, BinaryPredicate pred);
+
+template <typename RAIterator>
+std::vector<size_t> indirect_stable_sort (RAIterator first, RAIterator last);
+
+template <typename RAIterator, typename BinaryPredicate>
+std::vector<size_t> indirect_stable_sort (RAIterator first, RAIterator last, BinaryPredicate pred);
+```
+
+[heading Examples]
+
+[heading Iterator Requirements]
+
+`indirect_sort` requires random-access iterators.
+
+[heading Complexity]
+
+Both of the variants of `indirect_sort` run in ['O(N lg N)] time; they are not more (or less) efficient than `std::sort`. There is an extra layer of indirection on each comparison, but all of the swaps are done on values of type `size_t`
+
+[heading Exception Safety]
+
+[heading Notes]
+
+In numpy, this algorithm is known as `argsort`.
