In the theory of computation , a generalized nondeterministic finite automaton -LRB- GNFA -RRB- , also known as an expression automaton or a generalized nondeterministic finite state machine , is a variation of a. theory of computation. theory of computation. nondeterministic finite automaton. nondeterministic finite automaton. nondeterministic finite automaton -LRB- NFA -RRB- where each transition is labeled with any regular expression .. nondeterministic finite automaton. nondeterministic finite automaton. regular expression. regular expression. The GNFA reads blocks of symbols from the input which constitute a string as defined by the regular expression on the transition .. regular expression. regular expression. There are several differences between a standard finite state machine and a generalized nondeterministic finite state machine .. A GNFA must have only one start state and one accept state , and these can not be the same state , whereas a NFA or DFA both may have several accept states , and the start state can be an accept state .. A GNFA must have only one transition between any two states , whereas a NFA or DFA both allow for numerous transitions between states .. In a GNFA , a state has a single transition to every state in the machine , although often it is a convention to ignore the transitions that are labelled with the empty set when drawing generalized nondeterministic finite state machines .
