Summary
This additional chapter shows that both forward and backward reasoning are special cases of the resolution rule of inference. Resolution also includes compiling two clauses, like:
In the propositional case, given two clauses of the form:where B and D are conjunctions of atoms including the atom true, and C and E are disjunctions of atoms including the atom false, resolution derives the resolvent:The two clauses from which the resolvent is derived are called the parents of the resolvent, and the atom A is called the atom resolved upon.
