Asynchronous cellular learning automata
Cellular learning automata is a combination of cellular automata and learning automata. The synchronous version of cellular learning automata in which all learning automata in different cells are activated synchronously, has found many applications. In some applications a type of cellular learning automata in which learning automata in different cells are activated asynchronously (asynchronous ...
متن کاملFocused Crawling using Asynchronous Cellular Learning Automata
Web crawling is used to collect the web pages which will be indexed by a search engine. The search engine uses these crawled and indexed pages to answer users’ queries. Since the volume of web pages is very high and it increases continuously, search engines can index a limited number of web pages. Therefore, in recent years, the focused crawler algorithms have been introduced which act selectiv...
متن کاملWeighted Asynchronous Cellular Automata
We study weighted distributed systems whose behavior can be described as a formal power series over a free partially commutative or trace monoid. We characterize the behavior of such systems both, in the deterministic and in the non-deterministic case. As a consequence, we obtain a particularly simple class of sequential weighted automata that have already the full expressive power.
متن کاملReversibility in Asynchronous Cellular Automata
The reversibility issue of one-dimensional asynchronous cellular automata (ACAs) is addressed in this paper. The cells of ACAs are updated independently. The cellular automata (CAs) rules are classified as reversible and irreversible rules. The irreversible rules cannot configure reversible ACAs. The reversible rules may configure reversible ACAs depending upon the update of ACA cells. Finally,...
متن کاملAsynchronous cellular automata for pomsets
This paper extends to pomsets without auto-concurrency the fundamental notion of asynchronous cellular automata (ACA) which was originally introduced for traces by Zielonka. We generalize to pomsets the notion of asynchronous mapping introduced by Cori, Métivier and Zielonka and we show how to construct a deterministic ACA from an asynchronous mapping. Then we investigate the relation between t...
