该软件包包含多路分区算法:FMS(Fiduccia-Mattheyses-Sanchis)、PLM(通过锁定移动进行分区)、PFM(通过自由移动进行分区),详见 [DaAy97]。 图分区问题 图划分问题定义如下:给定一个输入图,将其划分为给定数量的几乎相等大小的部分,使得cutsize,即端点位于不同部分的边权重之和,被最小化。 这个问题有很多变化,并且在很...

Graph partitioning aims at balanced partitions with minimum interactions between partitions. However, graph clustering algorithms attempt to discover densely populated regions of graphs. We review algebraic algorithms for these problems and provide Python implementations of these algorithms in this chapter....
Graph Partitioning In this demo, we explore the graph partitioning problem. This is an interesting problem from graph theory with a wide variety of applications (see e.g.[3]). For example, suppose that we have a group of people that we need to split into two equal-sized teams. Between ...
PyMetis is a Python wrapper for theMetisgraph partititioning software by George Karypis, Vipin Kumar and others. It includes version 5.1.0 of Metis and wraps it using thePybind11wrapper generator library. So far, it only wraps the most basic graph partitioning functionality (which is enough ...
If it helps, my python-eque psuedocode works by performing a series of forward and backward graph traversals to identify all of the possible partitions.
given partitioning of the node set. Each partition of nodes (block) is represented as a single node in the reduced graph. Edges between nodes in the block graph are added according to the edges in the original graph. If the parameter multigraph is False ...
W是权重矩阵,V是顶点,它们构成对G=(V,W),即是权重图G。 The underlying graph of G isG^=(V,E)G^=(V,E)with E={{vi,vj}∣wij>0}E={{vi,vj}∣wij>0} Ifwij∈{0,1},W=Awij∈{0,1},W=A, the adjacency matrix ofG^G^ ...
