WebThe Resolution Proof Procedure To prove 𝜑from Σ, via a Resolution refutation: 1. Convert each formula in Σ to CNF. 2. Convert (¬𝜑)to CNF. 3. Split the CNF formulas at the ∧s, yielding a set of clauses. 4. From the resulting set of clauses, keep applying the resolution inference rule until either: • The empty clause results.

WebProof by Resolution: Example 3. Either taxes are increased or if expenditures rise then the debt ceiling is raised. If taxes are increased, then the cost of collecting taxes rises. If a rise in expenditures implies that the government borrows more money, then if the debt ceiling is raised, then interest rates increase. If ... In mathematical logic and automated theorem proving, resolution is a rule of inference leading to a refutation complete theorem-proving technique for sentences in propositional logic and first-order logic. For propositional logic, systematically applying the resolution rule acts as a decision procedure for formula unsatisfiability, solving the (complement of the) Boolean satisfiability problem. For first-order logic, resolution can be used as the basis for a semi-algorithm for the unsatisfiabili…
