动态规划 70.climbing Stairs
1. 记忆化搜索 - 自上向下的解决问题:使用vector来保存每次计算的结果,如果下次再碰到同样的需要计算的式子就不需要重复计算了。 2. 动态规划 - 自下向上的解决问题 解法一:自顶向下 解法二:自底向上 注意:从2只能移动到3和4;从3只能移动到6和5. 思路:设从位置(i,j)达到底部的最 ...

模拟退火算法
一. 爬山算法 ( Hill Climbing ) 介绍模拟退火前,先介绍爬山算法。爬山算法是一种简单的贪心搜索算法,该算法每次从当前解的临近解空间中选择一个最优解作为当前解,直到达到一个局部最优解。 爬山算法实现很简单,其主要缺点是会陷入局部最优解,而不一定能搜索到全局最优解。如图1所示:假设C点 ...
