Johnson, David S. (ed.) et al., Cliques, coloring, and satisfiability. Second DIMACS implementation challenge. Proceedings of a workshop held at DIMACS, October 11–13, 1993. Providence, RI: American Mathematical Society. DIMACS, Ser. Discrete Math. Theor. Comput. Sci. 26, 377-393 (1996).
Summary: To evaluate the performance of SAT algorithms empirically, we have already proposed a new type of random test-instance generator with known answers and proved securities. In this paper, we mainly discuss its controllability of several attributes such as the literal distribution, the clause-size distribution and the number of satisfying truth assignments. The generation algorithm has been implemented into four different generators, which have been used to test a Davis-Putnam algorithm and a local search algorithm to examine how the former works for unsatisfiable predicates of low clause/variable ratio and how the latter’s efficiency depends on the number of solutions.
