NBA

In computer science, the term „NBA“ typically refers to „Non-deterministic Buechi Automaton.“ It is a type of finite state machine used in automata theory and formal verification. An NBA is an extension of a non-deterministic finite automaton (NFA) that operates over infinite input sequences. What distinguishes an NBA from other types of automata is its acceptance condition: an infinite sequence is accepted if there exists at least one run of the automaton through that sequence which visits a set of designated „accepting“ states infinitely often.

In the context of model checking and verification, NBAs are crucial for determining properties of systems that exhibit non-deterministic behavior, particularly in the realms of reactive systems and real-time computing. They play a pivotal role in algorithms for automatic verification methods such as temporal logic.

The concept is foundational in theoretical computer science, providing insights into properties of systems and enabling rigorous proofs about system behaviors in relation to specifications.
