Evolutionary Programming (EP) and Differential Evolution (DE) are well known as simple and efficient schemes for global optimization over continuous spaces. Both EP and DE use mutation for producing offspring. The mutation operators of EP usually generate the search step size for mutation by probability distribution functions while the mutation operators of DE generate it by adding a weighted difference...
In order to achieve a satisfactory optimization performance by evolutionary programming (EP), it is necessary to ensure proper balance between global exploration and local exploitation. It is obvious that one single mutation operator is not the answer. Moreover, early loss of genetic diversity causes premature trapping around locally optimal points of the fitness landscape. This paper presents a fitness...
OpenStreetMap (OSM) is a world-wide campaign for developing open source maps. The prospect of such open source maps is very bright in commercial, educational and political points of views. With the burgeoning growth of mobile phones, the necessity of location based services is increasing day by day. Starting from the 3G mobile applications to cheap SMS-based services, we need maps everywhere. Various...
