In this paper, the issue of adapting migration parameters for MGAs is investigated. We examine, in particular, the effect of adapting the migration rates on the performance and solution quality of MGAs. Thereby, we propose an adaptive scheme to adjust the appropriate migration rates for MGAs. If the individuals from a neighboring sub-population can greatly improve the solution quality of a curr...

Migration of Virtual Machine (VM) is a critical challenge in cloud computing. The process to move VMs or applications from one Physical Machine (PM) to another is known as VM migration. In VM migration several issues should be considered. One of the major issues in VM migration problem is selecting an appropriate PM as a destination for a migrating VM. To face this issue, several approaches are...

the present paper that was based on the documentation method and secondary analysis of data from censuses population and housing statistics center of iran, intended to thoroughly analyze the effects of these factors in rural migration on rural aging population in addition, the increase in aging of iranian employees in agriculture sector and its consequences were examined. results have shown tha...

migration and quality of redistribution of population across country is one of the main factors that planners take into account to control population and guide its movements to economic poles. scientific recognition of migration phenomenon is important for managing and policy making in the country. these movements change migration pattern, in a way that along with increase in population and the...

We show that the unstructured ancestral selection graph applies to part of the history of a sample from a population structured by restricted migration among subpopulations, or demes. The result holds in the limit as the number of demes tends to infinity with proportionately weak selection, and we have also made the assumptions of island-type migration and that demes are equivalent in size. Aft...

This paper presents a biogeography-based optimization (BBO) algorithm to solve the economic loadDispatch (ELD) problem with generator constraints in thermal plants. The applied method can solvethe ELD problem with constraints like transmission losses, ramp rate limits, and prohibited operatingzones. Biogeography is the science of the geographical distribution of biological species. The modelsof...
