In other words, whatever state the FSA is in, if it encounters a symbol for which a transition exists, there will be just one transition and obviously as a result, one follow up state. A deterministic finite state automaton has exactly one transition from every state for each possible input. If “n” is the maximum number of states in NFA then 2 n is the maximum number of states to its corresponding DFA.Finite state automata (FSA), also known as finite state machines (FSM), are usually classified as being deterministic (DFA) or non-deterministic (NFA). Therefore the DFA with all its final states is given under,ĭFA has higher number of states as compare to NFA states. Step 4: Now draw DFA according to above transition table as belowĪs q2 was the final state in NFA, So all those states will be the final in DFA where q2 exist. Q0q2 becomes the third row and q0q1q2 will be the 4 th row of DFA table. We need to find the transitions for new generated states. We can see in above second row of DFA transition table, the new states q0q2 and q0q1q2 occurs. So the second row of DFA transition table will becomes as If any new state comes into picture then we will find the transition for that state. We can see in above row, transition for q0 is already found but the q0q1 is new state. Step 03: Now convert NFA transition Table To its corresponding DFA transition Tableįirst consider the first row of NFA transition table which will becomes the first row of DFA transition table. NFA transition table of above NFA is given below NFA graph for given example is given below Convert this NFA to its corresponding DFA. NFA of all binary strings in which 2nd last bit is 1. Step 05: If “x” was the final state in NFA, then all those states will be the final in DFA where “x” exist.Step 04: Through DFA transition Table draw DFA graph.Step 03: Now convert NFA transition Table To its corresponding DFA transition Table.There are five basic steps for conversion of NFA to DFA. In this section, we will discuss the method of conversion from NFA to DFA. As we know every NFA can be converted into corresponding DFA.
