Abstract

We show that any randomized logspace algorithm (running in polynomial time with bounded two-sided error) can be simulated deterministically in polynomial time and O(log²n) space. This puts RL in SC, "Steve's Class" In particular, we get a polynomial time, O(log²n) space algorithm for the st-connectivity problem on undirected graphs. Subject classifications. 68Q10, 68Q15, 68Q25.
