Webb11 nov. 2016 · 2.2 Hypergraph Partitioning A hypergraph H= (V, E) is a generalization of a graph in which an edge (usually called hyperedge or net) can connect any number of nodes. As with graphs, partitioning a hypergraph also means to find an assignment of nodes to different blocks of (mostly) equal size. earth\u0027s best purple canWebb1 jan. 2024 · We proposed a fast parallel streaming multilevel graph partitioning method.
