graph_simp - converts a graph to a simple undirected graph
12
: graph list of the old graph
15
: graph list of the new graph
17
\fVgraph_simp\fR returns the simple undirected graph \fVg1\fR corresponding to
18
multigraph \fVg\fR. It deletes loops in \fVg\fR, replaces directed edges
19
with undirected edges and replaces multiple edges with single edges.
