Predicate logic is an extension of propositional logic. Here we consider what is called first-order predicate logic, abbreviated FOL (sometimes abbreviated PL1, not to be confused with the programming ...

This article, the second in a series of three, deals with the classical logics which will give rise to mathematical logic at the end of the 19th century. The logic of propositions is first presented, ...

In classical planning, we aren't constrained to symbols that only take on true or false values, as we were in propositional logic. Instead, we introduce objects that can represent things in our ...

A (normal) system of propositional modal logic is said to be complete iff it is characterized by a class of (Kripke) frames. When we move to modal predicate logic the question of completeness can ...

Abstract: The paper introduces a predicate version of two-layered fuzzy probability logic, extending the known propositional probability logic based on the infinite-valued logic of Lukasiewicz. The ...

This repository contains Python implementations of the Propositional Logic and First Order Logic. In Propositional Logic, a model is simply an interpretation function. An interpretation function is a ...
