假设a1大于xi,按照Kruskal算法,首先考虑代价小的边,则执行Kruskal算法时,xi应该是在a1之前考虑,而a1又在a2,...,ak之前考虑,所以考虑xi之前,T中的边只能是E中的边,而xi既然没加入树T,就说明xi必然与E中的某些边构成回路,但xi和E又同时在U中,这与U是生成树矛盾,所以a1也不可能大于xi。 因此,新得到的树V...

在一些资料中,上述算法被称作 Double-tree algorithm。下面构造一个例子说明数字“2”是紧的: 例:考虑完全图 G=(V,E), |V|=2n+1 ,其中 v_0 与任何一个顶点之间的距离都是 1; v_{i} 与v_{i+1} 之间的距离为 1, i=0,\dots 2n-1; 其余所有两点间距离都是 2; 那么算法构造出的欧拉回路 L ...
