In subject area: Computer Science Resolution refutation is a procedure that refutes the satisfiability of a set of clauses and serves as a proof procedure for proving the validity of propositional formulas. It involves forming a set of clauses from a formula, such that the formula is a tautol...

We also use games to give upper bounds on proof size, and in particular describe a good strategy for the Prover in a certain game which yields a short refutation of the Linear Ordering principle. Using previous ideas we devise a new algorithm to automatically generate resolution refutations. On...
1. In a clause universal variable u is said to be blocked by an existential literal e in that clause if and only if [Math Processing Error]. A refutation of a QBF ϕ is a derivation of the empty clause. However, as is common in the literature, we will use the terms ‘refutation ...
of clauses is any ?nite tree of resolution inferences (instance of Cut) whose leaves (at the top) are clauses in ? and whose root (at the bottom) is . A refutation from ? is a resolution proof of ? from ? . The completeness of resolution, i.e., that there is a refutation from...
for every unit clause , any final instance of (Cut) in a refutation, which derives and therefore must be a cut between two unit clauses, is a -cut. So there must be a -cut below the lowest non- -cut. That is, contains the following configuration: ...

In mathematical logic and automated theorem proving, resolution is a rule of inference leading to a refutation theorem-proving technique for sentences in propositional logic and first-order logic. In other words, iteratively applying the resolution rule in a suitable way allows for telling whether a...
