WebMSP in a graph: Shortest Path between A and C: AD b) I guess that the uniqueness of MSP means that there is only 1 MSP MSP in a graph. So: First) Yes, if the weights of edges are not distinct, multiple MST may exist at the same time. In case of our graph, another possible MSP would include arc D-C instead of A-B (as an example). A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight.
