Separating complexity classes related to certain input oblivious logarithmic space-bounded Turing machines. (English) Zbl 0768.68017
Summary: In the following we prove that input oblivious simultaneously linear access-time and logarithmic space-bounded nondeterministic Turing machines are more powerful than deterministic ones. Moreover, we separate all the corresponding complexity classes $$L_{0,\text{lin}}$$, $$NL_{o,\text{lin}}$$, $$\text{co-}NL_{0,\text{lin}}$$ and $$P=AL_{0,\text{lin}}$$ from each other.
