本人在网站开发gis,游自编的最短路径查询程序，速度特快，3万节点，35000条路全部遍历，只需1秒。-I am in the site development gis, shortest path query self tour programs, speed express, 30,000 nodes, 35,000 road all the traverse, just 1 second.

本程序用模拟退火算法实现了图像的单阈值分割，分割效果良好。-The procedures used simulated annealing algorithm to achieve a single image threshold segmentation, segmentation with good results.
