Graph partitioning: an updated survey

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
Graph partitioning problem, which is one of the most important topics in graph theory, usually asks for a partition of the vertex set of a graph into pairwise disjoint subsets with various requirements. It comes from the well-known Max-Cut Problem: Given

Deep Multilevel Graph Partitioning

open access: yes29th Annual European Symposium on Algorithms (ESA 2021), 2021
Partitioning a graph into blocks of "roughly equal" weight while cutting only few edges is a fundamental problem in computer science with a wide range of applications. In particular, the problem is a building block in applications that require parallel processing. While the amount of available cores in parallel architectures has significantly increased

Graph Partitions in Chemistry

open access: yesEntropy, 2023
We study partitions (equitable, externally equitable, or other) of graphs that describe physico-chemical systems at the atomic or molecular level; provide examples that show how these partitions are intimately related with symmetries of the systems; and discuss how such a link can further lead to insightful relations with the systems’ physical and ...

Clique-partitioned graphs [PDF]

open access: yesDiscrete Applied Mathematics, 2022
A graph $G$ of order $nv$ where $n\geq 2$ and $v\geq 2$ is said to be weakly $(n,v)$-clique-partitioned if its vertex set can be decomposed in a unique way into $n$ vertex-disjoint $v$-cliques. It is strongly $(n,v)$-clique-partitioned if in addition, the only $v$-cliques of $G$ are the $n$ cliques in the decomposition.

Standard Framework for Comparison of Graph Partitioning Techniques

open access: yesJISR on Computing, 2015
Graph Partitioning is used to distribute graph partitions across nodes for processing. It is very important in the pre-processing step for distributed graph processing.

Adaptive Partitioning for Large-Scale Dynamic Graphs [PDF]

open access: yes, 2013
—In the last years, large-scale graph processing has gained increasing attention, with most recent systems placing particular emphasis on latency. One possible technique to improve runtime performance in a distributed graph processing system is to reduce

Buffered Streaming Graph Partitioning

open access: yesACM Journal of Experimental Algorithmics, 2022
Partitioning graphs into blocks of roughly equal size is a widely used tool when processing large graphs. Currently, there is a gap observed in the space of available partitioning algorithms. On the one hand, there are streaming algorithms that have been adopted to partition massive graph data on small machines.

Revisiting the Isoperimetric Graph Partitioning Problem

open access: yesIEEE Access, 2019
Isoperimetric graph partitioning, which is also known as the Cheeger cut, is NP-hard in its original form. In the literature, multiple modifications to this problem have been proposed to obtain approximation algorithms for clustering applications. In the

A Novel Partitioning Method for Accelerating the Block Cimmino Algorithm [PDF]

open access: yes, 2018
We propose a novel block-row partitioning method in order to improve the convergence rate of the block Cimmino algorithm for solving general sparse linear systems of equations.
