How a proof by resolution proceeds
Web1 Answer. The general resolution rule is that, for any two clauses (that is, disjunctions of literals) in your CNF such that there is i and j with P_i and Q_j being the negation of each other, you can add a new clause. P_1 v ... v P_ {i-1} v P_ {i+1} ... v P_n v Q_1 v ... v Q_ {j-1} v Q_ {j+1} ... v Q_m. This is just a rigorous way to say that ... WebHandbook of Proof Theory. Samuel R.

WebFor example, I have never seen a direct proof of the irrationality of $\sqrt{2}$. EDIT: As Carl Mummert said in his answer, the above part in italics is not true. There are propositions which are only provable by contradiction. A proof by contradiction can be also be formulated as a proof by contrapositive. WebWe look at the five rules to rule them all.
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.
