The versions of min_element
that return an iterator, return the iterator to the minimum value as
determined by using operator< if a predicate is not supplied. Otherwise
the predicate pred is
used to determine the minimum value. The versions of min_element
that return a range_return,
defines found in the
same manner as the returned iterator described above.
Defined in the header file boost/range/algorithm/min_element.hpp
For the non-predicate versions:
ForwardRange is a
model of the Forward
Range Concept.
ForwardRange's value
type is a model of the LessThanComparableConcept.
For the predicate versions:
ForwardRange is a
model of the Forward
Range Concept.
BinaryPredicate is
a model of the BinaryPredicateConcept.
ForwardRange's value
type is convertible to both of BinaryPredicate's
argument types.
Linear. Zero comparisons if empty(rng), otherwise distance(rng) - 1
comparisons.
