Social science research is concerned with the study of processes and phenomena in human societies, institutions and organizations. Social phenomena are complex due to many non-linear interactions between their elements. Social simulation represents a new paradigm for understanding social...

Cryptanalysis refers to finding the plaintext from the given cipher text. The problem reduces to finding the correct key from a set of possible keys, which is basically a search problem. Many researchers have put in a lot of effort to accomplish this task. Most of the efforts used conventional...

Page rank plays an important role in processing of an indexed list for relevant web pages/ clouds by search engines. Validation of computed page rank is significantly important towards the reliability enhancement for a computed page rank. Besides, energy efficiency is a major concern towards...

The communication of private information is very dangerous, since unauthorized entities can intercept it. Thus, encryption is one of the principal information security solutions that helps keep information confidentiality. This latter can be satisfied by the use of various encryption techniques,...

The density classification task (DCT for short) is one of the most studied benchmark problems for analyzing emergent computations performed by cellular automata. Starting from the observation that the performance of the best known solutions is not stable towards initial configurations size; we...

Cellular automata (CA) are discrete dynamical systems consist of a regular finite grid of cell; each cell encapsulating an equal portion of the state, and arranged spatially in a regular fashion to form an n-dimensional lattice. A cellular automata is like computers, data represented by initial...

This text was written as part of the project "Modelling of Complex Systems for Public Policy". It reviews the classical authors who jointly contributed to establish the elements of what could constitute a "science of complexity". Based on the original writings of these authors, the text...

This study explores the dynamics of urban sprawl through the application of DYNAMA, a Cellular Automata (CA) based model. The model simulates the urban land use expansion process in a disaggregated field of land units taking into account a set of local characteristics of cells and neighborhood...

Cellular automata were used to model and to simulate phenomena in the area of physics, biology and medicine. In this paper it is now shown how the idea of cellular automata can be applied to optimization problems as well. As an example a cellular automaton is used as a basis for solving...
