 Mining maximal\lceil \rceil vertices) in g. Quasi-clique is one of the most natural definitions for dense structures useful in finding communities in social networks and discovering significant biomolecule structures and pathways. However, mining maximal quasi-cliques is notoriously expensive with the state-of-the-art algorithm scaling only to small graphs with thousands of vertices.
