I have asked a series of questions concerning capabilities of a certain class of exotic automata which I have called min-heap automata; the original question, and links to others, can be found here.
Two of my last questions seem to have been quickly dispatched; one completely, and the other mostly (I have edited it to make it more viable). In either event, I actually had one other question I meant to ask, and would be interested to lay this subject to rest for good and all. So here it is:
A two-stack PDA can simulate a Turing machine. A $k$-heap nondeterministic type-1 min-heap automaton cannot (it seems; see the linked question). What about a $k$-tape nondeterministic type-1 min-heap automaton augmented with a stack (similar to that of a PDA)? Can it simulate a Turing machine? If not, does an augmented $(k+1)$-heap nondeterministic type-1 min-heap automaton accept a class of languages which is a proper superset of languages accepted by augmented automata with only $k$ heaps?
Thanks, and I promise this is the last of these questions.
