Solving Weighted Max-SAT in a Reduced Search Space: A Performance Analysis. Pipatsrisawat, K., Palyan, A., Chavira, M., Choi, A., and Darwiche A. Split variables (as opposed to all the variables).įor more information, please refer to the following papers: One keyĪdvantage of this approach is that the solver only needs to branch on This bound computation method is utilized by aīranch-and-bound solver in order to find the optimal solution. The solution to the relaxed problem is only a bound for the solution to However, when dealing with problems having large treewidths,Ī method known as variable splitting is first employed in order to Once in d-DNNF form, a Max-SAT problem can then be solved effeciently in polynomial time. Clone is a branch-and-bound Max-SAT solver which uses a novel approachįor computing bounds by making use of a tractable language known as d-DNNF.Ī problem instance is first compiled into d-DNNF form using a
