WebThe deterministic and non-deterministic time hierarchy theorems have a diagonalization argument, which does not seem to work for semantic classes. This is why we don't have strong hierarchy theorems for semantic classes. The best result I'm aware of is a hierarchy theorem for BPTIME with 1 bit of advice: Fortnow, L WebSpace-Hierarchy Theorem in Theoretical CS. 1. Let n be the length of w. 2. Compute f ( n) using space constructibility and mark off this much tape. If later stages ever attempt to use more, r e j e c t. 3. If w is not of the form < M > 10 ∗ for some TM M, r e j e c t. 4.

The basic use of time-constructibility (and space-constructibility) is to clock the time a machines runs (or space it uses), i.e. we want to simulate a machine only for t ( n) steps on an input of length n, only using O ( t ( n)) steps. To do this, we need to compute the value of t ( n) in time O ( t ...
