Solving the hard Satisfiability Problem is time consumingeven for modest-sized problem instances. Solving the RandomL-SAT Problem is especially difficult due to the ratioof clauses to variables. This report presents a parallel synchronoussimulated annealing method for solving the RandomL-SAT Problem on a large-scale distributed-memorymultiprocessor. In particular, we use a parallel synchronoussimulated annealing procedure, called Generalized SpeculativeComputation, which guarantees the...
