Resolution and Binary Decision Diagrams Cannot Simulate Each Other Polynomially
There are many different ways of proving formulas in proposition logic. Many of these can easily be characterized as forms of resolution (e.g. [12] and [9]). Others use so-called...

Extended resolution simulates binary decision diagrams
We prove that binary decision diagrams [1] can be polynomially simulated by the extended resolution rule of [2]. More precisely, for any unsatisfiable formula , there exists an ex...

Ordered Binary Decision Diagrams, Pigeonhole Formulas and Beyond
Groote and Zantema proved that a particular OBDD computation of the pigeonhole formula has exponential size, and that limited OBDD derivations cannot simulate resolution polynomia...

Constraint Propagation as a Proof System
Abstract. Refutation proofs can be viewed as a special case of constraint propagation, which is a fundamental technique in solving constraint-satisfaction problems. The generalizat...
