Short communication: a larger clique for a DIMACS test Published: 2005/01/31, Updated: 2005/03/29 Andrea GrossoMarco LocatelliWayne J. PullanCategories Combinatorial Optimization Tags dimacs tests, heuristics, maximum clique problem Short URL: https://optimization-online.org/?p=9690 In the DIMACS benchmark suite for the maximum clique problem, the best known solution for test C2000.9 is a 78 nodes clique; optimality is not proved. We present a 79 nodes clique emerged during the testing of a heuristic algorithm. ArticleDownload View PDF
