Predicates

A predicate is a function defined with set of variables, which returns the result True or False. The output of a predicate is a Boolean value as a response when given a set of parameters:

Shown is a transition diagram for an NFA N. The ultimate goal of this question is toobtain the minimal DFA accepting the language of N. Follow the instructions in the steps outlined shown.(a) Write down the formal description of N.(b) Write down the ε-closure of each state of N. Then eliminate all ε-transitions from N. Draw atransition diagram for the result.(c) Perform the subset construction on the automaton you got as a result in part b) and draw atransition diagram for the resulting DFA. You only need to draw reachable subsets.(d) Minimize the DFA you obtained in part c). Draw a transition diagram for the minimal DFA. Showall your work. The DFA you get as the final result in (d) should have five states. If you endup with a DFA with fewer or more than 5 states, you probably made an error somewhere on the way
