Sublogarithmic Space-Bounded Multi-Inkdot Two-Way Alternating Pushdown Automata with Only Universal States
A hierarchical property based on the number of inkdots in the accepting powers of sublogarithmic space-bounded multi-inkdot two-way alternating pushdown automata with only universal states is investigated. For these automata, it is shown that k +1 inkdots are better than k inkdots for each k≥1.
