Prim designed (or rather, redesigned) a sequence of steps to find a graph's Minimum Spanning Tree using path weights. The algorithm's steps are these: Select a random node. Choose the path with the minimum weight connected to the chosen node. The path will lead you to a new node, position yourself there.
