2014-02-17 08:57:20 -0600 | commented answer | Using nauty_geng with variable number of vertices Thank you! This is very helpful! |

2014-02-12 06:39:09 -0600 | asked a question | Using nauty_geng with variable number of vertices I am trying to use the nauty graph generator to count the number of non-isomorphic graphs with specified properties, but I am hindered by the fact that it seems nauty_geng only allows a fixed number of vertices. For example, the following code counts the number of (non-isomorphic) connected graphs on 5 vertices: The Sage output is: 21. However, if I try to count the number of connected graphs on ,the count remains equal to zero for each Is this the meaning of "At a minimum, you must pass the number of vertices you desire," a statement in the help box? Is there any way around this?
Thanks for any help with this! |
