To better understand what we’re trying to accomplish we will make a list of regular expressions that will then pass into a helper function to construct a list of NFAs. This list is what we will then glue together into one single NFA.

Conversion of Regular Expression to Finite Automata

WebIn the definition of a NFA the transition function takes as its inputs the current state and symbol to be processed, and produces a set of states. This is in contrast to a DFA whose transition function only produces a single state. For the problem given, it's true that the state diagrams of the NFA and the DFA will be identical. WebApr 21, 2010 · First Example: Design an NFA that accepts strings having the last two characters 00 or 11. The input symbols are Σ {0,1}. The given condition is last two characters should be 00 or 11. We discuss how to write logic for or condition in our DFA examples. NFA can move to multiple states.
