Propositional_Logic, first order logic, symbolic AI This project involves the implementation of a logical agent for navigating a modified Wumpus World environment using Propositional Logic.

First-Order-Logic Task1: Resolution with Refutation Propositional logic, also known as sentential logic or propositional calculus, is a branch of formal logic that deals with propositions, which are ...

Abductive problems have been widely studied in propositional logic. First order abduction, however, has been viewed as intractable, for the undecidability of logical consequence. In this paper, we ...

Definition (first-order predicate logic). First-order predicate logic or sentential logic or statement logic is a branch of logic that deals with quantified variables, so that rather than propositions ...

In traditional propositional logic(PL), the atomic part of formulas are proposition symbols. In first-order logic(FL) the atomic part of formulas are terms, predicates are relations among terms, and ...

A propositional system of modal logic is second-order if it contains quantifiers ∀p and ∃p, which, in the standard interpretation, are construed as ranging over sets of possible worlds (propositions).

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, ...

Consequently quantification over propositional variables can be modelled in IpC, and there is an interpretation of the second order propositional calculus, IpC2, in IpC which restricts to the identity ...

In propositional calculus we had WFFs. The corresponding thing in first order logic is called a first order formula. We will treat these very informally — if you want to learn about these in detail, ...
