CLIQUE(Clustering In QUEst)是一种简单的基于网格的聚类方法,用于发现子空间中基于密度的簇.CLIQUE把每个维划分成不重叠的区间,从而把数据对象的整个嵌入空间划分成单元.它使用一个密度阈值识别稠密单元和稀疏单元.一个单元是稠密的,如果映射到它的对象数超过该密度阈值. CLIQUE识别候选搜索空间的主要策略是使用稠密单元关于维度的单调性.这基于频繁模式和关联规则挖掘使用的先验性质.在子空间聚类的背景下,单调性陈述如下: 一个k-维(>1)单元c至少有I个点,仅当c的每个(…

先上最大团定义: 最大团问题(Maximum Clique Problem, MCP)是图论中一个经典的组合优化问题,也是一类NP完全问题,在国际上已有广泛的研究,而国内对MCP问题的研究则还处于起步阶段,因此,研究最大团问题具有较高的理论价值和现实意义. 最大团问题又称为最大独立集问题(Maximum Independent Set Problem).启发式算法.确定性算法有回溯法.分支限界法等,启发式算法.蚁群算法.顺序贪婪算法.DLS-MC算法和智能搜索算法等. 给定无向图G=(V,E).…

UVA 11324 - The Largest Clique 题目链接 题意:给定一个有向图,要求找一个集合,使得集合内随意两点(u, v)要么u能到v,要么v能到u,问最大能选几个点 思路:强连通分量,构造出scc之后,缩点,每一个点的权值是集合点个数,然后做一遍dag找出最大权值路径就可以 代码: #include <cstdio> #include <cstring> #include <vector> #include <stack> #includ…

Problem B: The Largest Clique Given a directed graph G, consider the following transformation. First, create a new graph T(G) to have the same vertex set as G. Create a directed edge between two vertices u and v in T(G) if and only if there is a path…
