operations_research::SetRangeIterator< SetRange > Class Template Reference

Detailed Description

template<typename SetRange>
class operations_research::SetRangeIterator< SetRange >

An iterator for sets of increasing corresponding values that have the same cardinality.

For example, the sets with cardinality 3 will be listed as ...00111, ...01011, ...01101, ...1110, etc...
