SAT solvers are algorithms designed to determine the satisfiability of boolean formulas. A boolean formula is a mathematical expression made up of variables that can be true or false, combined using logical operations like AND, OR, and NOT. The primary goal of a SAT solver is to find an assignment of truth values to the variables that makes the entire formula true. These solvers are widely used in various fields, including computer science, artificial intelligence, and hardware verification. They help solve complex problems such as circuit design, software testing, and optimization tasks by efficiently exploring possible variable assignments to find solutions.
