Nondeterministic finite automaton with ε-moves (NFA-ε) is a further generalization to NFA. In this kind of automaton, the transition function is additionally defined on the empty string ε. A transition without consuming an input symbol is called an ε-transition and is represented in state diagrams by an arrow … See more In automata theory, a finite-state machine is called a deterministic finite automaton (DFA), if • each of its transitions is uniquely determined by its source state and input symbol, and See more There are two ways to describe the behavior of an NFA, and both of them are equivalent. The first way makes use of the nondeterminism in the name of an NFA. For each input symbol, the NFA transitions to a new state until all input symbols have been consumed. In … See more A deterministic finite automaton (DFA) can be seen as a special kind of NFA, in which for each state and symbol, the transition function has exactly one state.

WebOct 9, 2013 · A state in an $\epsilon$-NFA may have any number of $\epsilon$-transitions to other states. But "any number" includes zero so an NFA (which has no $\epsilon$-transitions from any state) meets the definition of an $\epsilon$-NFA. If you like, an NFA is an $\epsilon$-NFA that happens not to have any $\epsilon$-transitions.
