OPEN-ended questionsAUTHORSIn this paper, we give a deterministic one-to-one pushdown transducer and a normal sequence of digits compressed by it. This solves positively a question left open in a previous paper by V. Becher, P. A. Heiber and the first author.CARTON, ...
Frequently Asked Questions What are the two types of pushdown automata? There are two types of Pushdown Automata (PDA): Deterministic Pushdown Automata (DPDA) and Nondeterministic Pushdown Automata (NPDA). DPDA has at most one possible transition for a given state and input, ensuring deterministic ...
They are also shown to be definable in a very natural way in terms of push-down automata. Using Rabin's theorem on the monadic second-order theory of the finite binary tree, these graphs are also shown to have a decidable monadic second-order theory. Questions about tiling systems and ...

Pushdown Automata & Parsing - Parsing is used to derive a string using the production rules of a grammar. It is used to check the acceptability of a string. Compiler is used to check whether or not a string is syntactically correct. A parser takes the in

Finally, we apply our results to decidability questions related to PDA, and obtain solutions in deterministic polynomial time. 展开 关键词: pushdown automata pushdown store languages descriptional complexity decidability questions DOI: 10.1007/978-3-642-31623-4_16 被引量: 8 ...
Here, we suggest anatural and intuitive model that subsumes all the formalisms proposed so far by employing height-deterministic pushdown automata. Decidability and complexity questions are also considered.These keywords were added by machine and not by the authors. This process is experimental and ...
