The Second DIMACS Implementation Challenge: 1992-1993
Originator: Mark Brockington
NP Hard Problems: Maximum Clique, Graph Coloring, and Satisfiability, The Second DIMACS Implementation Challenge: 1992-1993.
Random graphs from Mark Brockington and Joe Culberson's generator that attempts to "hide" cliques in a graph where the expected clique size is much smaller.
(800 vertices, 207505 edges)
