摘要: We compare two prominent decision procedures for propositional logic: Ordered Binary Decision Diagrams (Obdds) and the Davis-Putnam procedure. Experimental results indicate that procedure outperforms Obdds in hard constraint-satisfaction problems, while are clearly superior Boolean functional equivalence problems from circuit domain, and, general, require schematization of a large number solutions share common structure. The methods illustrate different often complementary strengths constraint-oriented search-oriented procedures.
