For simple machine models, such as nite automata or pushdown automata, many decision problems are solvable. In par- ticular, after formally introducing push-down automata in Section 14.1, we introduce two notions of acceptance - by final state and by empty stack - in Sections 14.1.2 and 14.1.3, respectively.
