The position of a world point’s solar shadow depends on its geographical location, the geometrical relationship between the orientation of the sunshine and the ground plane wher...
—Genetic algorithm (GA) is too dependent on the initial population and a lack of local search ability. In this paper, an improved greedy genetic algorithm (IGAA) is proposed to o...
We point out that for two sets of measurements, the sign of the difference of their averages is not necessarily maintained by a non-linear monotone transformation of the individu...
We propose the use of the Gabriel graph for the exploratory analysis of potentially high dimensional labeled data. Gabriel graph is a subgraph of the Delaunay triangulation, which ...
We prove the existence of small core-sets for solving approximate k-center clustering and related problems. The size of these core-sets is considerably smaller than the previously...
