In this paper we propose using cellular automata (CAs) to perform distributed scheduling tasks of a parallel program in the two processor system. We consider a program graph as a CA with elementaty cells interacting locally according to a certain rule which must be found. Effective rules for a CA are discovered by a genetic algorithm (GA). With these rules, CA-based scheduler is able to find allocations...
New results concerning application of cellular automata (CAs) to secret key cryptography is described in this paper. One dimensional nonuniform CAs are considered for generating pseudorandom number sequences used in a secret key cryptographic system. The quality of PNSs highly depends on set of applied CA rules. The search of rules relies on an evolutionary technique called cellular programming. Different...
In the report we have discussed a few aspects of SOC concept which in general have strongly influence on explicitness of mapping process. SOC idea is based on group of models and/does not seem to give quite clear instructions whether mapped phenomena exhibit SOC or not. To present the problem we have performed a computer simulation in order to investigate the effect of the critical point within the...
The paper presents basic description methods of critical phenomena, i.e. first-order, continuous phase transitions, and an overview of the self-organized criticality concept. In this approach an attempt is made to identify the determinant factors of modeling critical events using cellular automata.
Cellular Automata have been successfully applied to several scientific problems such as among others image processing or data encryption. One could find reversibility of dynamics is a fundamental feature of nature. While the most CA are not reversible in nature, one can find some CA with simple behavior could be reversible. Reversible cellular automata (RCA) as efficient encryption and decryption...
