Let a partial deterministic finite automaton be a DFA in which each state need not have a transition edge for each letter of the alphabet. We demonstrate that the smallest partial DFA for the set of all subwords of a given wordw, |w|>2, has at most 2|w|−2 states and 3|w|−4 transition edges, independently of the alphabet size. We give an algorithm to build this smallest partial DFA from the inputwon-line in linear time.
