RUSPACE(log n) is contained in DSPACE(log^2 n / loglog n)

Authors: Eric Allender and Klaus-Joern Lange

ABSTRACT
We present a deterministic algorithm running in space O(log^2 n/ loglog n) solving the connectivity problem on strongly unambiguous graphs. In addition, we present an O(log n) time-bounded algorithm for this problem running on a parallel pointer machine.
