Abstract

There are two main results proved here. The first states that a certain set SP of strings (those coding ''solvable path systems'') has tape complexity (log n)^2 iff every set in (i.e., of deterministic polynomial time complexity) has tape complexity (log n)^2. The second result gives evidence that SP does not have tape complexity (log n)^k for any k.
