WebThek-way partition problem is frequently solved by recursive bisection. That is, we rst obtain a 2-way partition ofV, and then we further subdivide each part using 2-way partitions. After logkphases, graphGis partitioned intokparts. WebPrevious multilevel graph partitioning methods such as Metis have suffered from the restriction of equal-sized clusters; our multilevel algorithm removes this restriction by using kernel k-means to optimize weighted graph cuts. Experimental results show that our multilevel algorithm outperforms a state-of-the-art spectral clustering algorithm ...

Web1 ian. 2015 · The next phase of an MLRB technique is to find a k-way partitioning by recursive bisection. First, Gi is subdivided into 2-way partitions, and then each part is further subdivided into 2-way partitions or bisections. Thus, a k-way partition can be solved by performing a sequence of 2-way partitions. WebThe k-way hypergraph partitioning problem is the generalization of the well-known graph partitioning problem: partition the vertex set into k disjoint blocks of bounded size (at …

Web4 aug. 2006 · For example, a 128-way partitioning of graphs with one million vertices can be computed in a little over two seconds on a 128-processor Cray T3D. Furthermore, the quality of the partitions produced is comparable (edge-cuts within 5%) to those produced by the serial multilevel k-way algorithm. Web1 ian. 1998 · In this paper, we present and study a class of graph partitioning algorithms that reduces the size of the graph by collapsing vertices and edges, we find ak-way partitioning of the smaller graph, and then we uncoarsen and refine it to construct ak-way partitioning for the original graph.

WebHypergraph partitioning is an important problem with extensive application to many areas, including VLSI design [Alpert and Kahng, 1995], efficient storage of large databases on disks [Shekhar and Liu, 1996], and data mining [Mobasher et al., 1996; Karypis et al., 1999b] .
