What is the error code you are getting when you try to add 33554431 vertices with igraph_add_vertices? Also, note that the parameter to igraph_add_vertices is *not* the ID of the vertex to add but the *number* of vertices to add. -- T. _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
