在本文中,我们考虑了大两部分图中的最大匹配问题。我们提出了一种新算法,该算法在新的边缘采样技术的一些迭代中找到了最大匹配。该算法可以在大数据设置(例如流式设置和MAPREDUCE设置)中实现,其中每个算法映射的每次迭代均分别通过流,或一个MapReduce Compul of Computation。我们证明,我们的算法为1/\ EPS回合中的最大匹配提供了1- \ eps的近似解决方案,从而改善了先前的工作,从而改善了通过/回合的数量。当我们在实际数据集上运行它时,我们的算法甚至可以更好地效果,并且在4到8发中找到了确切的最大匹配,同时仅采样总边缘的百分比1%。
In this paper we consider the maximum matching problem in large bipartite graphs. We present a new algorithm that finds the maximum matching in a few iterations of a novel edge sampling technique. This algorithm can be implemented in big data settings such as streaming setting and MapReduce setting, where each iteration of the algorithm maps to one pass over the stream, or one MapReduce round of computation, respectively. We prove that our algorithm provides a 1-\eps approximate solution to the maximum matching in 1/\eps rounds which improves the prior work in terms of the number of passes/rounds. Our algorithm works even better when we run it on real datasets and finds the exact maximum matching in 4 to 8 rounds while sampling only about %1 of the total edges.
