Optimizing and minimization of a Deterministic Finite Automata

AI Thread Summary
The discussion focuses on the minimization of a Deterministic Finite Automaton (DFA), where the original poster seeks clarification on their approach after receiving a different answer from a textbook. They express confusion over the discrepancies and request an explanation of their mistake. A respondent points out that the original poster's answer does not represent a valid DFA and suggests that the correct answer can be quickly verified through inspection. The conversation emphasizes the importance of understanding the minimization process and the potential pitfalls in applying complex methods unnecessarily. Understanding the correct approach to DFA minimization is crucial for accurate results.

so this is the question , I have to minimize this DFA

this is How I did it

can someone please explain to me what mistake I made? I have been wondering about this for past 2 days

No idea but your answer is not even a single DFA. The book answer is clearly correct and can be determined quickly by inspection*: are you sure you are expected to use an eigenvalue method to get to the answer?

*Note that there are no paths to q2 and q4 and q3 accepts so the path to q5 is irrelevant
