简单分布加权匹配

Simple Distributed Weighted Matchings

Jaap-Henk Hoepman

摘要:

Wattenhofer [WW04]提出了一种复杂的分布式算法来计算任意加权图的加权匹配,即距离该图的最大加权匹配至多5倍。我们表明,一个明显的顺序贪心算法[Pre99]的变体,计算加权匹配最多一个因素2远离最大值,很容易分布。这就产生了迄今为止最著名的分布式近似算法。

英文摘要:

Wattenhofer [WW04] derive a complicated distributed algorithm to compute a weighted matching of an arbitrary weighted graph, that is at most a factor 5 away from the maximum weighted matching of that graph. We show that a variant of the obvious sequential greedy algorithm [Pre99], that computes a weighted matching at most a factor 2 away from the maximum, is easily distributed. This yields the best known distributed approximation algorithm for this problem so far.
