 Method of analytic tableaux

The Method of Analytic Tableaux, also known simply as tableaux or semantic tableaux, is a formal proof system used in logic, particularly in the context of propositional logic and first-order logic. It is a decision procedure that allows for the systematic exploration of the truth values of logical formulas to determine their satisfiability or validity. ### Key Features of Analytic Tableaux: 1. **Tree Structure**: The method employs a tree-like structure to explore the implications of logical formulas.
