First Order Logic in AI (Artificial Intelligence)

First-order logic (FOL) in artificial intelligence (AI) is a formal system for representing and reasoning about the world using quantifiers, variables, predicates, and logical connectives. It extends propositional logic by introducing quantifiers like "for all" (∀) and "there exists" (∃), enabling precise specification of relationships and properties within a domain. FOL allows AI systems to express complex statements about objects, their attributes, and relationships between them, making it suitable for knowledge representation and automated reasoning tasks. Its ability to handle variables and quantify over them makes FOL fundamental in AI for encoding knowledge bases, inference rules, and logical reasoning processes.
