一直以为梯度下降很简单的,结果最近发现我写的一个梯度下降特别慢,后来终于找到原因:step size的选择很关键,有一种叫backtracking line search的梯度下降法就非常高效,该算法描述见下图: 下面用一个简单的例子来展示,给一个无约束优化问题: minimize y = (x-3)*(x-3) 下面是python代码,比较两种方法 #-*- cod...

回溯线搜索(Backtracking line search) 网上的两个算法流程: 1. 2. 关于这两个算法流程只需了解即可,因为上面这两个流程都不是很严谨,这里只作为了解之用。 ===

Now, node 2 becomes the next E-node or line node. Further, try the next node in the ascending nodes i.e., the node 3 which is having x2 = 2 means queen 2 is placed in the second column but by this the queen 1 and 2 are on the same diagonal, so node 3 becomes dead here ...
