Search Search Applications of Deterministic Finite Automata Search Search Deterministic Finite Automata Deterministic Finite Automata, or DFAs, have a rich background in terms of the mathematical theory underlying their development and use. This theoretical foundation is the main emphasis of ECS 120’s coverage of DFAs. However, this handout will focus on examining real-world applications of DFAs to gain an appreciation of the usefulness of this theoretical concept. DFA uses include protocol analysis, text parsing, video game character behavior, security analysis, CPU control units, natural language processing, and speech recognition. Additionally, many simple (and not so simple) mechanical devices are frequently designed and implemented using DFAs, such as elevators, vending machines, and traffic-sensitive traffic lights. As the examples below will demonstrate, DFAs naturally lend themselves to concisely representing any system which must maintain an internal definition of state.
