So dp[i] is the minimum value a subsequence of length i+1 might end with. Having this info, for each new number we iterate to, we can determine the longest subsequence where it can be appended using binary search. The final answer is the length of the longest subsequence we found so ...
Given a sequence of integers, find the longest increasing subsequence (LIS). You code should return the length of the LIS. Clarification What's the definition of longest increasing subsequence? The longest increasing subsequence problem is to find a subsequence of a given sequence in which the su...
The longest increasing subsequence problem is to find a subsequence of a given sequence in which the subsequence elements are in sorted order, lowest to highest, and in which the subsequence is as long as possible. This subsequence is not necessarily contiguous. Longest increasing subsequences are ...
SPOJ Another Longest Increasing Subsequence Problem 题意: 给定N个数对 \((x_i,y_i)\),求最长上升子序列的长度。上升序列定义为满足\((x_i,y_i)\)对i<j有 \(x_i<x_j\) 且 \(y_i<y_j\) 题解: 一个三维最长链问题 第一维是存位置,第二维存x,第三维存y 注意查询是查询到p[i].z-1...
The longest increasing subsequence problem is to find a subsequence of a given sequence in which the subsequence's elements are in sorted order, lowest to highest, and in which the subsequence is as long as possible. This subsequence is not necessarily contiguous, or unique. ...

Ourdata structure supports a query for the longest increasing subsequence in$O(r+\\\log n)$ worst-case time and supports inserts anywhere in the sequence in$O \\\left(r\\\log{n/r}ight)$ worst-case time (where $r$ is the length of thelongest increasing subsequence). The same data ...

http://www.lintcode.com/en/problem/longest-increasing-subsequence/ 题目意思: 给一个数组nums,找出这个数组中最长的递增子集的个数,子集元素在数组中的顺序不能打破。 解题方法: DP: 创建一个数组dp,代表数组中每个元素前面有几个比它小的元素(递增),从到到尾遍历数组nums,在i位置时,j从i-1到0去查找比...
