The automata implementation of event-based systems was made with the help of the procedural approach to software development, [9] [10] hence the name “state-based programming”. When using this method, output actions are assigned to the arcs , loops or nodes of the transition graphs (in general case mixed Moore-Mealy automata are to be used ...
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 ...
The forerunner of this book appeared under the title Formal Languages and Their Relation to Automata in 1968. Forming a basis both for the creation of courses on the topic, as well as for further research, that book shaped the field of automata theory for over a decade, cf. (Hopcroft 1989). Hopcroft, John E.; Ullman, Jeffrey D. (1968).
JFLAP (Java Formal Languages and Automata Package) is interactive educational software written in Java for experimenting with topics in the computer science area of formal languages and automata theory, primarily intended for use at the undergraduate level or as an advanced topic for high school.
Automata theory is the study of abstract machines and automata, as well as the computational problems that can be solved using them. It is a theory in theoretical computer science with close connections to mathematical logic. The word automata comes from the Greek word
The automata in the Hellenistic world were intended as tools, toys, religious spectacles, or prototypes for demonstrating basic scientific principles. Numerous water-powered automata were built by Ktesibios, a Greek inventor and the first head of the Great Library of Alexandria; for example, he "used water to sound a whistle and make a model ...
In a typical distributed system where both process automata and communication channel automata exist, they are composed in a way that output actions of one automaton are matched and executed with identically-named input actions of the other automata. For example, consider a system composed of two process, P i and P j, and a communication ...
For example, the language L p of even-length palindromes on the alphabet of 0 and 1 has the context-free grammar S → 0S0 | 1S1 | ε. If a DPDA for this language exists, and it sees a string 0 n , it must use its stack to memorize the length n , in order to be able to distinguish its possible continuations 0 n 11 0 n ∈ L p and 0 n 11 0 n +2 ...
