"WebThe edge weights determine the order in which the Dijkstra and Prim algorithms investigate (or attach) nodes. The sequence in which the nodes are examined (or connected) is constant if all of the edge weights are non-negative. This is because, even in the absence of a priority queue implementation, the algorithms will arbitrarily choose the ... " - Prims using priority queue
