"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. " - Dynamic tree cut algorithm

WebOct 15, 2024 · Clusters were identified using automatic module detection via dynamic tree cutting algorithm, using minimum module size 30. Cluster “eigengene” or metabolite, in this case, is defined as the first principal component of the metabolite abundances across replicates of each sample point ( Langfelder and Horvath, 2008 ). WebEuler Tours and Dynamic Trees Given a tree T, executing cut(u, v) cuts the edge {u, v} from the tree (assuming it exists). To cut T into T₁ and T₂ by cutting {u, v}: Let E be an Euler tour for T. Split E at (u, v) and (v, u) to get J, K, L, in that order. Delete the last entry of J. Then E₁ = K. Then E₂ = J, L
