WebAbstract. A data structure is proposed to maintain a collection of vertex-disjoint trees under a sequence of two kinds of operations: a link operation that combines two trees into one by adding an edge, and a cut operation that divides one tree into two by deleting an edge. Each operation requires O (log n) time. WebOct 15, 2024 · Clusters were identified using automatic module detection via dynamic tree cutting algorithm, using minimum module size 30.
