课程中, 作者将DP的问题分成以下几类:
1. 0/1 Knapsack, 0/1背包,6个题
0/1 Knapsack,0/1背包问题
Equal Subset Sum Partition,相等子集划分问题
Subset Sum,子集和问题
Minimum Subset Sum Difference,子集和的最小差问题
Count of Subset Sum,相等子集和的个数问题
Target Sum,寻找目标和的问题
2. Unbounded Knapsack,无限背包,5个题
Unbounded Knapsack,无限背包
Rod Cutting,切钢条问题
Coin Change,换硬币问题
Minimum Coin Change,凑齐每个数需要的最少硬币问题
Maximum Ribbon Cut,丝带的最大值切法
3. Fibonacci Numbers,斐波那契数列,6个题

House thief,偷房子问题
4. Palindromic Subsequence,回文子系列,5个题
Longest Palindromic Subsequence,最长回文子序列
Longest Palindromic Substring,最长回文子字符串
Count of Palindromic Substrings,最长子字符串的个数问题
Minimum Deletions in a String to make it a Palindrome,怎么删掉最少字符构成回文
Palindromic Partitioning,怎么分配字符,形成回文
5. Longest Common Substring,最长子字符串系列,13个题
Longest Common Substring,最长相同子串
Longest Common Subsequence,最长相同子序列
Minimum Deletions & Insertions to Transform a String into another,字符串变换
Longest Increasing Subsequence,最长上升子序列
Maximum Sum Increasing Subsequence,最长上升子序列和
Shortest Common Super-sequence,最短超级子序列
Minimum Deletions to Make a Sequence Sorted,最少删除变换出子序列

大家可以先把以上35个题目练熟,这样DP到达中等水平肯定是okay了的。再加以训练和提高。突破算法的硬骨头不在话下。一定要按照三种方式对照起来练。
