WebbThe multilevel k-way partitioning algorithms can compute a partitioning solution in which each partition is contiguous. All partitioning and ordering routines can compute multiple different solutions and select the best as the final solution. The mesh partitioning and mesh-to-graph conversion routines can operate on mixed element meshes. 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.
