Graph partition - Wikipedia

In graph theory, a minimum cut or min-cut of a graph is a cut (a partition of the vertices of a graph into two disjoint subsets) that is minimal in some metric. Variations of the minimum cut problem consider weighted graphs, directed graphs, terminals, and partitioning the vertices into more than two sets. The weighted min-cut problem allowing both positive and negative weights ca… WebMultipartite graph.

WebMar 20, 2016 · Graph partitioning and graph clustering are informal concepts, which (usually) mean partitioning the vertex set under some constraints (for example, the number of parts) such that some objective function is maximized (or minimized). We usually have some specific constraints and objective function in mind.

WebMar 21, 2024 · In graph theory, a network has a community structure if you are able to group nodes (with potentially overlapping nodes) based on the node’s edge density. This would imply that the original network G, can be naturally divided into multiple subgraphs / communities where the edge connectivity within the community would be very dense.

WebGraph partitioning is the problem of dividing the nodes of a graph into balanced par-titions while minimizing the edge cut across the partitions. Due to its combinatorial nature, many approximate solutions have been developed. We propose GAP, a Gen-eralizable Approximate Partitioning framework that takes a deep learning approach to graph ...
