1. Convert and minimize an ε-NFA for (a|b)*abb
Automata studentBackground
A student wants to verify the classic 11-state ε-NFA for the regular expression (a|b)*abb and inspect each determinization and minimization stage.
Problem
Construct the DFA and reduce it to a minimum equivalent machine.
How to use
Select Automata mode, enter the states, transitions, start state, accepting state, and alphabet, then enable Convert NFA to DFA and Minimize DFA.
Automaton definition: states 0 through 10; start state 0; accept state 10; alphabet a and b; include the ε-NFA transitions for (a|b)*abb.Outcome
The tutor shows a verified 5-state DFA with only E accepting, followed by a 4-state minimal DFA and the closure and partition-refinement rounds.
