TLA+ is a formal specification language used for designing, modeling, and verifying complex systems. It was created by Leslie Lamport, a computer scientist known for his work in distributed systems and formal methods. The acronym TLA stands for "Temporal Logic of Actions," which highlights its foundation in temporal logic—a way to reason about time-dependent behaviors in systems. TLA+ is particularly useful for specifying the behavior of concurrent and distributed systems, where multiple processes operate simultaneously.
