Genetic algorithms are heuristic search algorithm used in science, engineering and many other areas. They are powerful but slow because of their evolutionary nature that mimics the natural selection process. The quality of the solutions delivered depends on the population size, causing larger demand on processing power. Parallel and distributed processing techniques resolve this issue by alloca...

rural migration is the process of people moving from rural areas to cities. rural migration to urban is an important issue for all countries. in this study, investigate the causes of rural migration to urban in malayer conty (hamedan province). stutistic population in this study was people who have migrated from their village and data for this study has collected from the 180 migrant households...

Differential evolution (DE) is a prominent stochastic optimization technique for global optimization. After its original definition in 1995, DE frameworks have been widely researched by computer scientists and practitioners. It is acknowledged that structuring a population is an efficient way to enhance the algorithmic performance of the original, single population (panmictic) DE. However, only...

In the context of virtual machines live migration, two strategies called “pre-copy” and “post-copy” have already been presented; but each of these strategies works well only in some circumstances. In this paper, we have a brief presentation of QAVNS and then introduce a new approach which is based on the concept of "informational object", assigning QAVNS-scheme-revision number, and observing th...

in this paper, we have proposed a new algorithm which combines pso and ga in such a way that the new algorithm is more effective and efficient.the particle swarm optimization (pso) algorithm has shown rapid convergence during the initial stages of a global search but around global optimum, the search process will become very slow. on the other hand, genetic algorithm is very sensitive to the in...

International migration flows largely reflect demographic patterns and economic opportunities. Migration increase in expected income other pull factors potential destinations, push the origin, like high unemployment, low wages, population growth. decrease geographic cultural distance between origin destination, costs. To extent that migrants are employed, immigration can alleviate challenges ar...

According to the intelligent behavior of social population, the centroid of the individual best of particle swarm is firstly introduced in particle swarm optimization (PSO) model to enhance inter-particle cooperation and information sharing capabilities, then combining the mechanism of population migration algorithm (PMA), a novel PSO algorithm with adaptive space mutation (PMCPSO) is proposed ...

abstractagriculture is considered as one of the important sectors of economic. that in the production of food and industrial crops may play an important role in economic development. in this regard human resource is very important. so that quantitative and qualitative changes in the human resources can lead to major changes in agricultural production and it influences completely agricultural pr...
