NOMURA Programming Competition 2020 D Urban Planning
考虑排列 \(P_i\) 已经固定了的情况，那么连边 \(i\to P_i\) 形成有向图 \(G\)，最小连边数就是 \(N\) 减去弱连通块数。善良的出题人已经告诉你连边方案就是 \((N-1)^K\)，所以答案就是 \(N(N-1)^K\) 减去所有连边方案中弱连通块数量总和。于是只需要考虑所 ......

Greedy algorithm basic principle
贪心算法是以动态规划方法为基础的，在每个贪心算法之下，几乎总有一个更繁琐的动态规划算法。 贪心算法和动态规划不同之处在于：是否需要考虑子问题的解 贪心算法并不考虑子问题，直接在当前步骤中做出选择 动态规划无论是自底向上， 贪心算法设计步骤 将最优化问题转化为这样的形式：对其做出一次选择后，只剩下一个 ......
