== 他山之玉 ==

== 杂事杂项 ==

 * 关于wqs二分
   * 在很多整数题里，函数都是整点且相邻点斜率必为整数时，可以只二分整数
   * 二分的姿势应该是当>=K时，l=mid+1，最后的答案用l-1再跑一次dp，就算dp出来取得边数>K，也可以f+(l-1)*K，算出来是对的，这种就是共线的情况（注意dp过程中相同的f值取最多的边数）
 * 拉格朗日乘数法
   * 在约束条件G(x,y,z)=0下求函数F(x,y,z)的极值时，求出函数H(x,y,z,λ)=F(x,y,z)+λ*G(x,y,z)的驻点代入F即可
 * [wiki:2019-team0x03/like_euclid 类欧几里得算法]
 * Bell数 Touchard同余：（p是任意质数）B_{n+p}≡B_n+B_n+1 (mod p)
 * LCS有nlogn下限的求法： 考虑A中每个元素在B中的序号{p1,p2...pk}，将这些序号降序排列，再按A中顺序排在一起，新序列的最长严格递增子序列即A,B的LCS。 证明可以通过证新序列的严格递增子序列和A,B的公共子序列一一对应来证明。 这种做法在两个序列公共元素不多的情况下可以跑的很快。
 * unordered_map比手写的hash表快
 * -fno-stack-limit
 * 本质不同的回文串只有O(n)个，可以在回文自动机上枚举
 * 欧拉定理（就是那个系数k mod phi(mod)的定理）  k<phi时不用加，k>=phi时指数取模完要加上phi
 * n个串建了广义SAM后，比方说统计SAM上每个节点在多少个串上出现过，每个串扔进去跑，走到一个节点更新它的所有parent（跳parent时如果当前节点x在这个串已经出现过可以停下来因为x的parent一定也已经出现过了），这样做复杂度是O(L\sqrt n) 的（L是n个串的总长度），因为对于一个串T，更新一次的复杂度是 min(|T|^2^,L)的，T>\sqrt n时串不超过\sqrt n个，T<\sqrt n时，|T|^2^ * n/|T|=n|T|<= n \sqrt n
 * nth_element(first, nth, last)
 * 树上的连通块可以用dfs序上的k个区间并表示
 * bitset _Find_fisrt()就是找到从低位到高位第一个1的位置,_Find_next()就是找到当前位置的下一个1的位置(如果某个元素之后没有元素的话会返回bitset的大小)
 * sigma (ai+b)/c（下取整） 这类问题有经典解法类欧几里得

他山之玉

杂事杂项

  • 关于wqs二分
    • 在很多整数题里，函数都是整点且相邻点斜率必为整数时，可以只二分整数
    • 二分的姿势应该是当>=K时，l=mid+1，最后的答案用l-1再跑一次dp，就算dp出来取得边数>K，也可以f+(l-1)*K，算出来是对的，这种就是共线的情况（注意dp过程中相同的f值取最多的边数）
  • 拉格朗日乘数法
    • 在约束条件G(x,y,z)=0下求函数F(x,y,z)的极值时，求出函数H(x,y,z,λ)=F(x,y,z)+λ*G(x,y,z)的驻点代入F即可
  • 类欧几里得算法
  • Bell数 Touchard同余：（p是任意质数）B_{n+p}≡B_n+B_n+1 (mod p)
  • LCS有nlogn下限的求法： 考虑A中每个元素在B中的序号{p1,p2...pk}，将这些序号降序排列，再按A中顺序排在一起，新序列的最长严格递增子序列即A,B的LCS。 证明可以通过证新序列的严格递增子序列和A,B的公共子序列一一对应来证明。 这种做法在两个序列公共元素不多的情况下可以跑的很快。
  • unordered_map比手写的hash表快
  • -fno-stack-limit
  • 本质不同的回文串只有O(n)个，可以在回文自动机上枚举
  • 欧拉定理（就是那个系数k mod phi(mod)的定理） k=phi时指数取模完要加上phi
  • n个串建了广义SAM后，比方说统计SAM上每个节点在多少个串上出现过，每个串扔进去跑，走到一个节点更新它的所有parent（跳parent时如果当前节点x在这个串已经出现过可以停下来因为x的parent一定也已经出现过了），这样做复杂度是O(L\sqrt n) 的（L是n个串的总长度），因为对于一个串T，更新一次的复杂度是 min(|T|2,L)的，T>\sqrt n时串不超过\sqrt n个，T<\sqrt n时，|T|2 * n/|T|=n|T|<= n \sqrt n
  • nth_element(first, nth, last)
  • 树上的连通块可以用dfs序上的k个区间并表示
  • bitset _Find_fisrt()就是找到从低位到高位第一个1的位置,_Find_next()就是找到当前位置的下一个1的位置(如果某个元素之后没有元素的话会返回bitset的大小)
  • sigma (ai+b)/c（下取整） 这类问题有经典解法类欧几里得
