Maximum weight clique problem has some attention but i could not find any efficient approaches to this problem yet. I acknowledge that it is np-hard, but are there any known approximations?
Given a fixed n and an undirected graph, the problem can be defined as finding n disjoint cliques which maximize the sum of the vertex weights in these cliques. Disjoint cliques can be defined as cliques that do not have any common vertex.
I have taken a look on this dissertation but did not help much.
