Re: [igraph] max_cliques memory leak

[Gábor Csárdi]

Why do you think this is a memory leak?

Your graph probably has millions of billions of max cliques, and they
just don't fit into the memory.

There is an option to write them out to an output file as soon as they
are found, I suggest you try that.
