n层图划分

n-Level Graph Partitioning

Vitaly Osipov, Peter Sanders

摘要:

我们提出了一个多层次的图划分算法的基础上的极端的想法,合同只有一个单一的边缘上的层次结构的每一级。这消除了对匹配算法的需要,并保证了非常好的分割质量,因为两个级别之间的变化非常少。使用一个有效的数据结构和新的灵活的方法来打破局部搜索的改进早期,我们得到了一个算法,规模大的输入,并产生最好的已知的分区结果为许多输入。例如,在Walshaw著名的基准表中,我们实现了155项改进,这些改进主导了大型图的条目。

英文摘要:

We present a multi-level graph partitioning algorithm based on the extreme idea to contract only a single edge on each level of the hierarchy. This obviates the need for a matching algorithm and promises very good partitioning quality since there are very few changes between two levels. Using an efficient data structure and new flexible ways to break local search improvements early, we obtain an algorithm that scales to large inputs and produces the best known partitioning results for many inputs. For example, in Walshaw's well known benchmark tables we achieve 155 improvements dominating the entries for large graphs.
