昨天考试被教育了一波.为了学习一下\(T3\)的科技,我就找到了这个远古时期的\(cf\)题(虽然最后\(T3\)还是不会写吧\(QAQ\)) 顾名思义,这个题目其实可以建成一个费用流的模型.我们用流量来限制区间个数,用费用强迫它每次每次选择最大的区间就可以啦.但是因为询问很多,复杂度似乎不行,于是就有了这种神奇的科技--线段树模拟费用流. 在原先的费用流模型里,我们有正反两种边,而反向边的意义就在于,在每一次增广的时候可以反悔以前的操作,把局部最优向更大范围的局部更优优化. 参考反向边的原理,…

点此看题面 大致题意: 给你一个序列,让你支持单点修改以及询问给定区间内选出至多\(k\)个不相交子区间和的最大值. 题意转换 这道题看似很不可做,实际上可以通过一个简单转换让其变可做. 考虑每次选出一个区间,统计答案后将这个区间内所有数乘上\(-1\),再继续求答案,这样做是显然合法的. 于是就变成了在给定区间内选出权值和最大子区间和区间乘\(-1\)两种操作. 具体实现 具体实现十分复杂... 对于线段树的每个节点,我们需要维护区间和.最大值及其区间.前缀最大值及其区间.后缀最大值及其区间.…
