Logic Variables

Logic variables are placeholders used in programming and logical expressions that can represent different values during computation. They allow the program to reason about various possibilities without fixing a specific value upfront. For example, in a logical rule like "If X is a parent of Y," X and Y are logic variables that can stand for any individuals fitting the relationship. This flexibility enables complex reasoning, pattern matching, and querying in languages like Prolog, facilitating intelligent decision-making and knowledge representation by allowing variables to be instantiated dynamically based on the context.
