FindEdgeIndependentPaths

FindEdgeIndependentPaths[g,s,t,k]

finds at most k edge-independent paths from vertex s to vertex t in the graph g.

FindEdgeIndependentPaths[{vw,…},…]

uses rules vw to specify the graph g.

Details

  • Edge-independent paths are also known as edge-disjoint paths.
  • FindEdgeIndependentPaths returns a list of edge-independent paths from s to t.
  • Each path is given as a list of vertices.
  • FindEdgeIndependentPaths works with undirected graphs, directed graphs, multigraphs, and mixed graphs.
