Abstract
The simulation of two-way deterministic and nondeterministic pushdown automata is revisited. A uniform algorithm presented herein decides on a random-access machine in linear time resp. cubic time whether a given pushdown automaton accepts a word, while the actual run of the automaton may take exponential time. The algorithm is practical since it only explores reachable configurations, simulates a class of quasi-deterministic decision problems in linear time even if the pushdown automaton is nondeterministic, and iterates over a simple work list. This is an improvement over previous simulation algorithms.
