WebMar 2, 2024 · In bipartite graphs, a butterfly (i.e., $2\times 2$ bi-clique) is the smallest non-trivial cohesive structure and plays an important role in applications such as anomaly … Webcounting in a bipartite graph, as shown in Algorithm 1. Given a bipartite graph G = (LG ∪ RG,EG), the algo-rithm sequentially processes each vertex ℓ ∈ LG to compute γ(ℓ), along with γ(e) for each e = (ℓ,r) ∈ EG, as follows. Let 2hop(ℓ) be the set of vertices that are exactly two hops (i.e., two edges) away from ℓ.
