Minimum Cut Algorithms

Detailed Description

This group contains the algorithms for finding minimum cut in graphs.

The minimum cut problem is to find a non-empty and non-complete $X$ subset of the nodes with minimum overall capacity on outgoing arcs. Formally, there is a $G=(V,A)$ digraph, a $cap: A\rightarrow\mathbf{R}^+_0$ capacity function. The minimum cut is the $X$ solution of the next optimization problem:

$\min_{X \subset V, X\not\in \{\emptyset, V\}} \sum_{uv\in A, u\in X, v\not\in X}cap(uv)$

LEMON contains several algorithms related to minimum cut problems:

Hao-Orlin algorithm for calculating minimum cut in directed graphs.
Gomory-Hu tree computation for calculating all-pairs minimum cut in undirected graphs.

If you want to find minimum cut just between two distinict nodes, see the maximum flow problem.
