A Study of Proof Search Algorithms for Resolution and Polynomial Calculus
This paper is concerned with the complexity of proofs and of searching for proofs in two propositional proof systems: Resolution and Polynomial Calculus (PC). For the former syste...

NP-Completeness of Refutability by Literal-Once Resolution
A boolean formula in conjunctive normal form (CNF) F is refuted by literal?once resolution if the empty clause is inferred from F by resolving on each literal of F at most once. Li...

Statistical timing verification for transparently latched circuits through structural graph traversal
Level-sensitive transparent latches are widely used in high-performance sequential circuit designs. Under process variations, the timing of a transparently latched circuit will ada...

Drawing Trees with Perfect Angular Resolution and Polynomial Area
We study methods for drawing trees with perfect angular resolution, i.e., with angles at each vertex, v, equal to 2/d(v). We show:

Resolution cannot polynomially simulate compressed-BFS
Many algorithms for Boolean satisfiability (SAT) work within the framework of resolution as a proof system, and thus on unsatisfiable instances they can be viewed as attempting to...
