Hi Stefan,
I need only to find a maximum cardinality.
I mount the graph based in a correlation algorithm.
I`m looking for a implemented algorithm or if the graph stream have one implementation.

Thanks a lot,
Rodrigo.

Hi Rodrigo,

If you can wait, just use a brute force approach. Is your graph
weighted or you just want to find a maximum cardinality clique ?

Cheers,
