Improving The Fetch XML Performance using Latematerialize -如何使用Latematerialize提高Fetch XML 查询性能
假设要从包含 100,000 条记录、100 多列的表中提取 500 个,根据过滤条件,需要几分钟才能获取记录。 原因是应用程序传统上 fetchxml 首先获取所有 100,000 条记录和数百列。然后它根据查询执行过滤器以获取记录。 为了克服这一挑战,如果我们一个查询,首先提取所需 500 条记 ......

CF1890D Doremy's Connecting Plan
或许赛时根本不需要证明贪心的正确性。 我们发现 \(c\) 对于问题的影响不大,我们可以将每个 \(a_i\) 除以 \(c\),就转化为了 \(c=1\) 的情况。 一个自然的贪心是用 \(1\) 作为中心点去连接其他的所有点,这需要两条结论保证其正确性: 结论一: 如果当前图中还可以连边,点 \ ......

Codeforces Round 906 (Div. 2) Doremy's Drying Plan E1.&E2
传送门 先考虑\(E1\) 只需要删除两条线使得不被覆盖的点数最多。 观察到点数只有\(200000\) 那么我们完全可以先将被至少\(3\)条线覆盖的点删掉。 考虑枚举一条线,枚举这条线覆盖的点寻找另外一条线覆盖这些点中的最大值,然后再找没覆盖这些点之外的线的最大值即可。 复杂度容易证明是线性的。 ......

《CF1889C2 Doremy's Drying Plan (Hard Version)》 解题报告
考场上不会做。 如果考虑删掉哪些区间实际上不太可做。正难则反,转化贡献,考虑哪些点可以有贡献。 显然一个点如果可能有贡献,那么当且仅当覆盖它的区间 \(\le K\) 个。 于是我们记一个状态 \(f_{i,j}\) 表示前 \(i\) 个点中, \(i\) 是最后一个贡献的点,已经删除了 \(j\ ......

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 ......

容易想到 dp:设 \(dp_{i,p}\) 表示前 \(i\) 天,强制第 \(i\) 天 dry,并且一共消除了 \(p\) 个区间的答案。 转移时可以考虑枚举前面的决策 \(j\),此时有转移方程: \[dp_{i,p}=\max(dp_{j,p-w})+1 \]其中 \(w\) 为满足 \( ......
CF1889B. Doremy's Connecting Plan
一开始不会先跳 C 了!差点满盘皆输! 设 \(i<j\),则 \(i,j\) 合并可以看作 \(a_i\leftarrow a_i+a_j\) 后删掉 \(j\)!此时和初始局面本质相同!所以不妨先只看初始局面! 不等式右侧和下标有关!显然若右侧 \(i,j\) 中只要有一个是 \(1\),就会让 ......
