Automata-based programming is a programming technology. [1] Its defining characteristic is the use of finite-state machines to describe program behavior. The transition graphs of state machines are used in all stages of software development (specification, implementation, debugging and documentation).
Automata-based programming is a programming paradigm in which the program or part of it is thought of as a model of a finite-state machine (FSM) or any other (often more complicated) formal automaton (see automata theory). Sometimes a potentially infinite set of possible states is introduced, and such a set can have a complicated structure, not ...
Figure 4 depicts a composition of two processes, P i and P j and a FIFO message channel C i,j, matching output actions of one automaton with identically named input actions of other automata. Thus, a send(m) i,j output performed by process P i is matched and performed with a send(m) i,j input performed by channel C i,j .
Usually when speaking about suffix automata and related concepts, some notions from formal language theory and automata theory are used, in particular: [9] "Alphabet" is a finite set that is used to construct words. Its elements are called "characters";
In automata theory, a deterministic pushdown automaton (DPDA or DPA) is a variation of the pushdown automaton. The class of deterministic pushdown automata accepts the deterministic context-free languages, a proper subset of context-free languages. [1]
It is a computer program that generates lexical analyzers (also known as "scanners" or "lexers"). [ 3 ] [ 4 ] It is frequently used as the lex implementation together with Berkeley Yacc parser generator on BSD -derived operating systems (as both lex and yacc are part of POSIX ), [ 5 ] [ 6 ] [ 7 ] or together with GNU bison (a version of yacc ...
Golly is a tool for the simulation of cellular automata.It is free open-source software written by Andrew Trevorrow and Tomas Rokicki; [3] it can be scripted using Lua [1] or Python.
Local automata accept the class of local languages, those for which membership of a word in the language is determined by a "sliding window" of length two on the word. [ 6 ] [ 7 ] A Myhill graph over an alphabet A is a directed graph with vertex set A and subsets of vertices labelled "start" and "finish".
