洛谷 P9061 [Ynoi2002] Optimal Ordered Problem Solver

洛谷传送门 QOJ 传送门 考虑操作了若干次,所有点一定分布在一个自左上到右下的阶梯上或者在这个阶梯的右(上)侧。此处借用 H_W_Y 的一张图: 考虑如何计算答案。对于一次询问 \((X, Y)\),如果它在阶梯左下方不用管它,否则考虑容斥,答案即为 \(x \ge X, y \ge Y\) 的点 ......

5.4 Bounds on the optimal code length (Shannon-Fano coding)

From section 5.3, we have \(l_i^*=-\log_D p_i\), but it may not be integer, and we should choose \(l_i\) close to \(l_i^*\). So round it up using the ......

Worst-Case Optimal Joins

Worst-Case Optimal Joins 当且仅当连接算法的计算复杂度不高于AGM bound,该算法才是Worst-Case Optimal的。 而计算AGM bound,需要计算fractional edge cover,也就是最小边覆盖。它要求给每条边赋权,所有权重之和最小,并且每个顶 ......
