Condensation Graph
This algorithm condensate any graph by merge a set of edges in a condensed edge. The user can provide a predicate of edges to specify which edge to condensate or condense by components as well.
The AlgorithmExtensions class provide various helpers, Condensate...
, to condense graphs:
IVertexAndEdgeListGraph<TVertex, TEdge> g = ...; // input graph
var condensed = g.CondenstateWeaklyConnected();
