Resolution Proofs

Resolution Proofs. Requires axioms to be in clause form To do harder proofs, we convert their axioms to clause form Clause form is a disjunctions of literals How do we convert a set of axioms into clause form. Steps. Eliminate implications Move negations down to the atomic formula

RESOLUTION

RESOLUTION. WHAT IS RESOLUTION ?. Resolution is a technique for proving theorems in the propositional or predicate calculus. Resolution proves a theorem by negating the statement to be proved and adding this negated goal to the set of axioms . Resolution involve the following steps. .
