WebWhy Boost.Graph does not (yet) provide a contract_vertices() TL;DR I don't know. But I can speculate. Mainly, one should specify the interface of a putative contract_vertices(). Apart from the two vertices to be contracted, and the type of graph they are a part of, one should also define the merge and move operations on the edge properties. WebNow for some more graph terminology. If some edge (u,v) is in graph G, then vertex v is adjacent to vertex u.In a directed graph, edge (u,v) is an out-edge of vertex u and an in-edge of vertex v.In an undirected graph edge (u,v) is incident on vertices u and v..
