Büchi automata are a type of infinite-state automaton that recognize ω-regular languages, which are useful for modeling systems with ongoing behaviors. They are particularly important in formal verification, where they help analyze the correctness of systems over infinite sequences, like those described by Linear Temporal Logic (LTL). By utilizing Büchi automata, one can express and verify properties of systems that evolve over time, making them crucial for behavioral modeling in hardware and software verification.
congrats on reading the definition of büchi automata. now let's actually learn it.
