求图中的最大匹配是一个经典问题。该问题的在线版本(图的顶点和/或边一次给出一个,并且算法必须增量计算匹配)已经研究了二十多年。文献中考虑了这个问题的许多变体。开创性的工作(Karp, 1990)考虑了一个二部图,其中一个部分的顶点与它们的关联边一次显示一个。在本文中,我们考虑了极大的d-可色图,它就是完全的d-部图。顶点与它们的相关边一起一次到达一个,或者等价地在图的某个给定的d-着色中与它们相应的颜色一起到达。针对这一在线问题,我们提出了一个2/3竞争的最优确定性算法。该问题与星形拓扑光网络中线路终端成本最小化问题密切相关。我们考虑光路以在线方式到达给定的恒星网络。我们的结果暗示了一种紧密的10/9竞争算法,用于在这样的网络中寻找最小化线路终端成本的波长分配。
Finding a maximum matching in a graph is a classical problem. The on-line versions of the problem in which the vertices and/or edges of the graph are given one at a time and an algorithm has to calculate a matching incrementally have been studied for more than two decades. Many variants of the problem are considered in the literature. The pioneering work (Karp, 1990) considers a bipartite graph where the vertices of one part are revealed one at a time together with their incident edges. In this work we consider maximal d-colorable graphs which are exactly the complete d-partite graphs. The vertices arrive one at a time together with their incident edges, or equivalently with their corresponding colors in some given d-coloring of the graph. We present an optimal 2/3-competitive deterministic algorithm for this on-line problem. This problem is closely related to that of minimizing the cost of line terminals in star topology optical network. We consider lightpaths arriving in an on-line fashion on a given star network. Our result implies a tight 10/9-competitive algorithm for finding a wavelength assignment minimizing the cost of line terminals in such a network.
