This paper presents selective coloring as a new paradigm for branch-and-bound exact maximum clique search. Approximate coloring has, in recent, years been at the heart of leading solvers in the field. Selective coloring proposes to relax coloring up to a certain threshold. The result is a less informed but lighter decision heuristic. Different operators for(More)
We present a new implicit branching strategy for maximum clique. The new strategy is based in Konj and Janecic's improvement over reference MCR algorithm. It uses a fixed initial non increasing degree vertex ordering at every step of the search, to obtain tighter bounds than MCR on average. We show that the new branching strategy integrates nicely with a(More)
