In this paper,we have considered the state minimization problem for Deterministic Finite Automata (DFA). An efficient parallel algorithm for solving the problem on an arbitrary CRCW PRAM has been proposed. For n number of states and k number of inputs in Σ of the DFA to be minimized,the algorithm runs in O(kn log n) time and uses O( n/log n ) processors.
