vgtcrossmentions an elegant alternative approach in the followingcomment. This also aids in the understanding of the algorithm for vertex MST as the rules of adding an edge when seen through the lens of this approach makes the algorithm identical to the kruskal's algorithm for MST!
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...
