Instead of starting from an edge, Prim’s algorithm starts from a vertex and keeps adding lowest-weight edges which aren’t in the tree, until all vertices have been covered. We have three separate groups of participants, each of whom gives us a single score on a rating scale. Kruskal Minimum Cost Spanning Treeh. •Pick the smallest edge that connects two different trees • The abstract description is simple, but the implementation affects the runtime.
