Hello. First of all, thank you for producing igraph. I am new to igraph and have been working with a colleague who uses the program, cliquer, to find the maximum clique size of a given graph. Given a set of edges in a graph, I have been
trying to use the clique_num() function in igraph to return the size of the maximum clique. This is the only output needed – the number of points -- we do not need to store all possible cliques. Cliquer can do this very quickly using a branch and bound algorithm
developed by Patric Östergård. Is there a more appropriate function than clique_num() that can return the number of points in a clique that is maximal?
Thank you for your consideration.
