NBA

In computer science, NBA stands for „Nondeterministic Büchi Automaton.“ It is a type of automaton used in formal verification and model checking to represent and analyze systems that exhibit certain behaviors over infinite computations.

An NBA is a theoretical model that extends the concept of a finite automaton to handle infinite inputs, often used in the context of verifying properties of systems that operate indefinitely, such as concurrent and reactive systems. The primary characteristic of an NBA is that it can accept infinite strings of inputs, and acceptance is determined based on reaching a set of „accepting“ states infinitely often.

In formal language theory and automata theory, an NBA plays a crucial role in expressing properties that may require the analysis of infinite paths, making it valuable for applications in software and hardware verification, particularly in checking the correctness of systems against specifications in temporal logic.
