 The header file `<boost/algorithm/cxx11/is_sorted.hpp>` contains functions for determining if a sequence is ordered.

-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_equal is used (i.e, the test is to see if the sequence is non-decreasing)
