A bipartite graph in igraph has a ‘ type ’ vertex attribute giving the two vertex types. This function simply checks whether a graph could be bipartite. It tries to find a mapping that gives a possible division of the vertices into two classes, such that no two vertices of the same class are connected by an edge.
