Hello all,
I can extract all induced subgraphs and count them in a graph. My question is how I can search and count all induced subgraphs in a labeled graph (a graph with edge labels)? In documentation of g.subgraph() and g.subgraph_search_count() is mentioned that these functions should work on labeled graphs as well. but it does not work. Here is an example:
sage: g=DiGraph() sage: g.add_vertex(0) sage: g.add_vertex(1) sage: g.add_vertex(2) sage: g.add_edge(0,1,label="a") sage: g.add_edge(1,2,label="b") sage: g.plot(color_by_label="true") sage: g.plot(color_by_label=true)
sage: s=DiGraph() sage: s.add_vertex(0) sage: s.add_vertex(1) sage: s.add_edge(0,1,label="a") sage: s.plot(color_by_label=true)
sage: g.subgraph_search_count(s) 2
While it should return 1 not 2.
