Graph Partitioning Problem (GPP)是NP困难的。即使是对于最大度为3的无权树来说。 该问题经常通常使用启发式的方案 其他的一些调查研究 [23] 涉及了很多方法以及图分区的应用。比如multilevel method, metaheuristic, parallel methods, hypergraph partitioning [159] 关注于科学计算的技巧。包括可调节的动态模拟,以及...
Description of the graph partitioning problem The graph partitioning problem has several facets. One of the most used is the unsupervised K-way partitioning that can be defined as follows: let G=(V,E) be an undirected graph, where V=v1,v2,…,v|V| represents the set of vertices (i.e....
The graph partitioning problem 图割问题旨在对图进行分区,使得: 不同组之间的边的权重非常低。 同一组内的边的权重较高。 图割问题可以用以下方式表达: graph cut problem \text{cut}(A_1, \ldots, A_k) 定义为: \text{cut}(A_1, \ldots, A_k) := \frac{1}{2} \sum_{i=1}^k W(A_i...

directed partitioning problems that we study. Then in Section 4 we show that integrality gaps of an SDP relax- ation for the Bipartite Directed Sparsest Cut Problem, and for an LP relaxation for the Directed Sparsest Cut Problem have natural embedding formulations. In Sec- tion 5 we show har...
However, the task of finding a ground state of three-dimensional Ising spin systems has been proven to be NP-hard, while its decision problem version is NP-complete9,10. Other NP-complete problems, such as the MAX-CUT problem, graph partitioning problem and some families of SAT problems ...
Graph partitioningInteger programmingBranch & CutIn this work, a multi-constraint graph partitioning problem is introduced. The input is an undirected graph with costs on the edges and multiple weights on the nodes. The problem calls for a partition of the node set into a fixed number of ...

Graph partitioning is a key problem to enable efficient solving of a wide range of computational tasks and querying over large-scale graph data, such as computing node centralities using iterative computations, and personalized recommendations. In this work, we introduce a unifying framework ...
