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 ...

In this chapter, we introduce a new algorithm for finding a minimum spanning tree (MST) of an undirected neutrosophic weighted connected graph whose edge weights are represented by an interval valued neutrosophic number. In addition, we compute the cost of MST and compare the de-neutrosophied va...
