K-d tree implementation in C++ for NN and KNN search Templated k-d tree example that makes use of boost geometry point classes. The k-d tree is build in bulk and supports N dimensions. The implementation contains a recursive and iterative ne

基于k-d树的knn算法实现，实现较简单，供初学参考。-Knn, K-D tree

字典树设集合S由若干单词（英文）组成，给定字符串K，在S中查找与K最佳匹配的结果。最佳匹配的结果定义为：与K有最长共同前缀的字符串。 例：S={abc, bdef, zhen, zhao, abdd}，K1=zhao，K2=abdf，K3=cheng，则与K1最匹配的结果是zhao，与K2最匹配的结果是abdd，与K3最匹配的结果是ε（空串）。 -Dictionary tree set S by a number of words (English), given the string
