Proof complexity and backtracking algorithms

1. The resolution inference rule takes two premises in the form of clauses (A ∨ x) and (B ∨ ¬x) and gives the clause (A ∨ B) as a conclusion.
2. Proof complexity is the study of the size of the smallest proof a method can produce [28].

## What is the resolution principle?

The resolution principle, due to Robinson (1965), is a method of theorem proving that proceeds by constructing refutation proofs, i.e., proofs by contradiction. This method has been exploited in many automatic theorem provers. Unification is a key technique in proofs by resolution. …

## What is resolution principle in AI explain with example?

Resolution is a theorem proving technique that proceeds by building refutation proofs, i.e., proofs by contradictions. It was invented by a Mathematician John Alan Robinson in the year 1965.
