A cut C in a network is a set S of nodes that is neither empty nor the entire set of nodes. The weight of a cut is the sum of the weights of the edges having exactly one endpoint in S.
|int||MIN_CUT(const graph& G, const edge_array<int>& weight, list<node>& C, bool use_heuristic = true)|
|MIN_CUT takes a graph G and an edge_array weight that gives for
each edge a non-negative integer weight.
The algorithm () computes
a cut of minimum weight. A cut of minimum weight is returned in C
and the value of the cut is the return value of the function.
The running time is
O(nm + n2log n). The function uses a heuristic to speed up its computation.
Precondition The edge weights are non-negative.
|list<node>||MIN_CUT(const graph& G, const edge_array<int>& weight)|
|as above, but the cut C is returned.|
|int||CUT_VALUE(const graph& G, const edge_array<int>& weight, const list<node>& C)|
|returns the value of the cut C.|
