WebJan 10, 2024 · The Louvain algorithm is used for finding them modular communities, while in the case of DCS, then the Charikar algorithm is used. Each extracted sub-graph of the alignment graph represents a connected sub-graph of the unweighted networks and a subgraph of the conceptual network with the given properties (density or modularity) WebGiven an n-vertex graph with nonnegative edge weights and a positive integer k ≤ n, our goal is to find a k-vertex subgraph with the maximum weight. We study the following greedy algorithm for this problem: repeatedly remove a vertex with the minimum weighted-degree in the currently remaining graph, until exactly k vertices are left.
