Introduction: About 60 percent of the world's pasture land (about 2.2 million sq km), just less than half the world's usable surface is covered by grazing systems. These are distributed between arid, semi arid and sub humid, humid, temperate and tropical highlands zones. This supports about 360 million cattle (half of which are in the humid savanna...

A dynamic version of Environmental Adaption Method (EAM) is proposed in this paper. Environmental Adaption Method for Dynamic Environment (EAMD) is an improvement over EAM, which works in dynamic environment with real valued parameters. Unlike EAM the theory of this algorithm is based on adaption of species in dynamic environment which gradually be...

The methods of searching optimal solutions are distinct in different evolutionary algorithms. Some of them do search by exploiting whereas others do by exploring the whole search space. For example Genetic Algorithm (GA) is good in exploitation whereas the Environmental Adaption Method (EAM) performs well in exploring the whole search space. Indivi...

Change in any software application seems to be very simple when someone demands it, but the complexity of the task appears during implementation phase. Change implementation is acceptable when it includes the requested functionality as well as improves and preserves the quality of software.
