|Title: ||A lower bound for the shortest path problem|

|Abstract: ||We show that the shortest path problem cannot be solved in o(log n) time on an unbounded fan-in PRAM without bit operations using poly(n) processors, even when the bit-lengths of the weights on the edges are restricted to be of size O(log(3) n). This shows that the matrix-based repeated squaring algorithm for the shortest path problem is optimal in the unbounded fan-in PRAM model without bit operations. (C) 2001 Academic Press.|
