yes it seems so Vertex ID, vertex label, vertex ID, vertex label, direction if you know a graph dataset generator please provide it?

Hello, I need a graph dataset file like this format: ( 1968974,47,3151724,41,undirected 2794386,16,2794394,6,undirected 13311,26,128801,28,undirected ) If anyone knows a name or source for dataset like the above(other than patents and youtube), please let me know. Best, Maya

Hi, Thank you Dr. Philippe for your reply and help. Actually I am intersted in the 2nd point wich you mentioned in your reply: 2) You could do sampling to reduce the search space during the search for frequent subgraphs. Instead of checking all subgraphs in the search space, you will skip some of them. But then, the result would become approximate. If you remember the best sampling met
