# Union of two dfa

Give the state diagram of a DFA that recognizes the language fw j w ends with 00g. Answer: The key idea is to design three states q0;q1;q2, where q0 speciﬂes the input string does not end with 0, q1 speciﬂes the input string ends with exactly one 0, and q2 speciﬂes the input string ends with at least two 0s. Nov 10, 2017 · This DFA will accept Set of all strings which have even number of 0s AND two consecutive 0s at the end and nothing else. If you are wondering what would have been the Union of the two DFAs - The Union is the exact same machine except the difference in the Final/Accept states. Below is the Union of the two DFAs. tells us that the union of two DFA-regular languages is DFA-regular. Thus we have closure under union as well as intersection and complement. By induction, any Boolean combination of DFA-regular languages is DFA-regular. 3 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.
