最大割问题(Max-cut Problem)是指对给定的有向加权图求取一个最大分割,使横跨两个割集的所有边上的权值之和最大。是图论中一个典型的NP难组合优化问题。 最大割问题在统计物理、图像处理等工程问题中有着广泛的应用。虽然理论上该问题可以由枚举法找到,但是在实践过程中往往不可能实现。因为运行时间随着问题规模...

问题描述:无向图G =(V, E),一条割线将图的所有点分为两个子集,要求割线经过的边权重和最大 NP-hard问题,没法直接求解,需要近似方法求解。 G = [03580306411560208420100110100] 使用线性规划进行松弛 定义决策向量,顶点类别Xv, 边的类别Ze。 {Xv}v∈V∈{0,1} 点在0部分,还是1部分 {Ze}e∈E∈{0,1...
量子计算-P3.PyQUBO使用-Max Cut 问题 简介: Maximum Cut 问题,俗称最大割问题,NP-hard。给定一张,求一种分割方法,将所有顶点(Vertex)分割成两群,同时使得被切断的边(Edge)数量最大。 转化: 此问题最大化形式为: PS:参数(-2)可调节,只要将(0,0),(0,1)/(1,0),(1,1)分割开即可,并且使得(0,1...
Given an undirected graph with edge weights, the MAX-CUT problem consists in finding a partition of the nodes into two subsets, such that the sum of the weights of the edges having endpoints in different subsets is maximized. It is a well-known NP-hard problem with applications in several ...
Given an undirected graph G = (V, E) with a set V of vertices, and a set E of edges with weights, the max–cut problem consists of partitioning all vertices into two independent sets such that the sum of the weights of the edges between different sets is maximised. The max–cut prob...
