Non-Standard Conforming Parallel Algorithms

[zhekemist]

The following HPX algorithms deviate from the C++ standard:

• hpx::generate: The HPX algorithm returns a past-the-end iterator, while the standard specifies that the return type should be void. (See in the standard draft.)
• hpx::search: The overload that takes a range and a searcher is missing. (However, this is probably not very critical, as there is no parallel version of this algorithm anyway.) (See in the standard draft.)
• hpx::search_n: HPX's search_n is effectively equivalent to search(first, std::next(first, n), s_first, s_last), but according to the standard, search_n should find a contiguous sequence of n identical elements equal to a given value. (See in the standard draft.)
