Transition function of a NFA - Mathematics Stack Exchange

WebDeterministic finite automata - a state machine for which each transition for a state is uniquely determined by it’s input symbol as each state can only have a single move per input symbol. In a DFA, for a particular input character, machine goes to one state only. A transition function is defined on every state for every input symbol.
