but I can’t talk about that and games without going into the more fundamental concept offinite state machines(or “FSMs”). But then once I went there, I figured I might as well introducehierarchical state machinesandpushdown automata. ...
Pushdown automata – More complicated than finite state machines, these use regions of memory called stacks to store information as part of a model. Linear-bounded automata (LBA) – Similar to a Turing machine, but the data is limited to a portion of input within a finite group of inputs....
A formal definition of Bottom-up Embedded Push-Down Automata and their tabulation technique Summary: The task of designing parsing algorithms for tree adjoining grammars could be simplified by providing a separation between the description of the parsing strategy and the execution of the parser. This...

In this paper, we represent deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) biological sequences using state grammar and deep pushdown automata. The major benefit of this approach is that the DNA and RNA sequences can be parsed in linear time O(n) , where n is the length of the ...
This paper establishes the closure of the family of languages recognized by input-driven pushdown automata (IDPDA), also known as visibly pushdown automata, under the quotient operation. A construction of automata representing the result of the operation is given, and its state complexity with ...
