基于网络流的多级超图划分精化

Network Flow-Based Refinement for Multilevel Hypergraph Partitioning

Tobias Heuer, Peter Sanders, Sebastian Schlag

摘要:

我们提出了一个改进的框架,使用最大流计算对块的多级超图分区,以提高解决方案的质量的$k$路分区。该框架将KaFFPa基于流的改进算法从图推广到超图,并集成到超图划分器KaHyPar中。通过减小超图流网络的大小,改进KaFFPa中使用的流模型,并开发技术来提高算法的运行时间,我们获得了一个分区器,该分区器可以计算来自不同应用领域的各种基准超图的最佳解决方案,同时仍然具有与hMetis相当的运行时间。

英文摘要:

We present a refinement framework for multilevel hypergraph partitioning that uses max-flow computations on pairs of blocks to improve the solution quality of a $k$-way partition. The framework generalizes the flow-based improvement algorithm of KaFFPa from graphs to hypergraphs and is integrated into the hypergraph partitioner KaHyPar. By reducing the size of hypergraph flow networks, improving the flow model used in KaFFPa, and developing techniques to improve the running time of our algorithm, we obtain a partitioner that computes the best solutions for a wide range of benchmark hypergraphs from different application areas while still having a running time comparable to that of hMetis.
