【算法训练-动态规划零】动态规划解题框架

动态规划问题的一般形式就是求最值。动态规划其实是运筹学的一种最优化方法，只不过在计算机问题上应用比较多，比如说求最长递增子序列呀，最小编辑距离呀等等。既然是要求最值，核心问题是什么呢？求解动态规划的核心问题是穷举。因为要求最值，肯定要把所有可行的答案穷举出来，然后在其中找最值呗。动态规划基本概念动态...

【算法训练-回溯算法零】回溯算法解题框架

抽象地说，解决一个回溯问题，实际上就是遍历一棵决策树的过程，树的每个叶子节点存放着一个合法答案。你把整棵树遍历一遍，把叶子节点上的答案都收集起来，就能得到所有的合法答案。站在回溯树的一个节点上，你只需要思考 3 个问题：路径：也就是已经做出的选择。选择列表：也就是你当前可...
