摘要
二部图的最小边着色是将边划分为&Dgr;匹配，其中&Dgr;是图中的最大度。提出了使用时间为O(min(…)&Dgr;log n，……@@@@n log n, n2log &Dgr;))和空间0 (n&Dgr;)这比之前的O(…[等式]log &Dgr;)时间限制有利。着色算法也能在正则(或半正则)二部图上找到最大匹配。除了当[方程]≤&Dgr;≤@@@@n log n。
A minimum edge coloring of a bipartite graph is a partition of the edges into &Dgr; matchings, where &Dgr; is the maximum degree in the graph. Coloring algorithms are presented that use time O(min(¦E¦ &Dgr; log n, ¦E¦ @@@@n log n, n2log &Dgr;)) and space O(n&Dgr;). This compares favorably to the previous O(¦E¦ [equation] log &Dgr;) time bound. The coloring algorithms also find maximum matchings on regular (or semi-regular) bipartite graphs. The time bounds compare favorably to the O(¦E¦ @@@@n) matching algorithm, expect when [equation] ≤ &Dgr; ≤ @@@@n log n.
