MinCostArborescence< GR, CM, TR >::DualIt Class Reference

Detailed Description

template<typename GR, typename CM, typename TR>
class lemon::MinCostArborescence< GR, CM, TR >::DualIt

This class provides a common style LEMON iterator for getting a dual variable of MinCostArborescence algorithm. It iterates over a subset of the nodes.
