慢SQL的模板化算法优化

变更背景当前慢SQL链路会对每条SQL进行SQL模板化处理，即对原始SQL去除变量参数后得到SQL模板，再对SQL模板进行加密获得SQLHASH。例如，原始SQL为select name, age, score from study where age > 20 and score > 10时：SQ...

【图像分割】基于回溯搜索优化算法实现图像聚类分割附matlab代码

1 内容介绍阈值法是一种简单且有效的图像分割技术.但是随着阈值数目的增加,求解阈值的计算量增大并且实时性降低,这给多阈值图像分割带来了很大的困难.为了克服这一困难,把多阈值分割看作一个优化问题.将最大类间方差法当作要优化的函数,用回溯搜索优化算法求解要优化的函数,从而实现多阈值图像分割.将提出的多阈值算法应用于基准测试图像上,并与传统阈值分割法比较.实验结果表明:回溯搜索优化算法很好....
