In this paper we consider two branch and bound algorithms for the maximum clique problem which demonstrate the best performance on DIMACS instances among the existing methods.

(<CitationRef CitationID="CR31">2010</CitationRef>) and MAXSAT algorithm by Li and Quan (<CitationRef CitationID="CR21">2010a</CitationRef>, <CitationRef CitationID="CR22">b</CitationRef>). We suggest a...</citationref></citationref></citationref>
