最近点对问题，输入数据生成器自动生成2位点对，输出制定电的最近邻-nearest point of the problem, the input data generator automatically generate two points right, electrical output of the nearest neighbor

主要是KNN（the k-nearest neighbor　algorithm ）,LVQ1（learning vector quantization 1）, DSM（decision surface mapping）算法。 and a simple clustering algorithm.

基于R树的K近邻查询算法及递增的k近邻查询算法实现-the implemention of R-tree K-nearest neighbor query algorithm and incremental nearest neighbor query algorithm
