However, for demo purposes, one can run part of the program as a Java. I have included a word file with some examples too.it will be helpful. finite automaton (DFA), DFA to minimum state DFA, NFA to regular grammar. transitions from state for character / Constructs the DFA from the arrays, as specified in the overall header / NFA(String ss. The input to the program should be given like this:įirst, understand the process completely then try understanding the code. It follows the general rules and ways to convert an e-NFA to DFA which are:Ģ)epsilon of the starting state of e-NFA is considered as the starting state for DFA.-(consider it to be X)ģ)Find all the states reached by each of the individual states present in the starting state of DFA.-(if X is ABC then find states from A on 0 and Same for B and C)Ĥ)Find their epsilons and union them.-(if A on 0 gives B, C then (B's epsilon UNION C's epsilon) UNION if B on 0 gives B then (B's epsilon) UNION if C on 0 gives - then (NONE)).ĥ)repeat the above steps till there is no new state available.įor more visually understanding it go to youtube and type e-NFA to DFA and you will get millions of videos. In our C program, we will represent an NFA as a. I have written a c++ program that converts an Epsilon-Nondeterministic finite automaton(e-NFA) to a deterministic finite automaton(DFA). The first step is to compile the regular expression into an equivalent NFA.
