Unification In First Order Logic : Useful Links
What is Unification? · Unification is a process of making two different logical atomic expressions identical by finding a substitution. · The UNIFY algorithm is used for ...
Resolution Example: FOL. Example: Prove bird(tweety). Axioms: Regular. CNF. 1 : 2: 3: 4: Resolution Proof. 1. Resolve 3 and 1, specializing (i.e. “unifying”) ...
Unification is a "pattern matching" procedure that takes two atomic sentences, called literals, as input, and returns "failure" if they do not match ...
Syntactical first-order unification is used in logic programming and ...
The unification algorithm is simple. if both sides are constants (numbers, strings, atoms, etc.) the result unifies it it is the same one; if one side is ...
The unify algorithm takes two sentences and returns a unifier for them ...
Abstract. We introduce unification in first-order transitive modal logics, i.e. logics extending Q–K4, and apply it to solve some problems such as ...
Reducing first-order inference to propositional inference. Unification. Generalized Modus Ponens. Forward and backward chaining. Logic ...
Unification is originally concerned with finding a substitution that makes two terms equal with respect to a given equational theory. In logic, ...
