An augmenting path is a simple path - a path that does not contain cycles - through the graph using only edges with positive capacity from the source to the sink.

### A Shortest Augmenting Path Algorithm for the Semi

As part of this process we will need to find an augmenting path.

Ford-Fulkerson Algorithm is also known as Augmenting Path algorithm.A path P from s to t in D f is called an augmenting path for D with respect to.

### Ford Fulkerson algorithm - cse.unt.edu

A flow f is a max flow if and only if there are no augmenting paths.

Color classes of edges in a proper edge coloring form matchings. Matchings. with M-unsaturated vertices is an M-augmenting path. every path or cycle in F.A matching in a graph is a sub set of edges such that no two.A common sequential approach to AP is to use the shortest augmenting path (SAP) method, which treats AP as a special case of the minimum cost network flow problem.Two theorems to recall: Theorem 3.1.10 (Berge).A matching M in a graph G is a maximum matching in G iff G has no M-augmenting path.

A network is at maximum flow if and only if there is no augmenting path in the residual network G f.We can increase the value of f by increasing the flow on every edge of p by up.
