AREED Computers & Systems Dept., Faculty of Engineering, Mansoura University ABSTRACT: – This work is concerned with studying an effective evolutionary algorithm based on neuron level beside blueprint level search algorithm. This algorithm maintains diversity in the population due to the evolution of partial solutions (neurons) instead of full solutions (networks). …

للكاتبين : Hassan Shaheen and Amir Atiya Department of Computer Engineering Faculty of Engineering, Cairo University , Giza , EGYPT ABSTRACT This work deals with the problem of forecasting a complex environment behavior. The word “complex behavior” is here used in the sense that the environment may be modeled as an almost random walk environment. Stock market prediction is known …

للكاتبين : El-Desouky N., Ghali N., Zaki M. Faculty of Science (for girls)- Al-Azhar University- Cairo – Egypt ABSTRACT In this paper we propose a new approach to weight variation in Particle Swarm Optimization (PSO) called Exponential Particle Swarm Optimization (EPSO). EPSO depends on exponential variation for the inertia weight; which under all testing cases makes the particle swarm converges …
