I am applying DFS on this graph and I am not sure if this is correct because on theory DFS takes the first node and that implementation is easy when the graph isn't weighted so we apply alphabetically order. In other cases, it is more natural to associate with each connection some numerical "weight". Can I hang this heavy and deep cabinet on this wall safely? The is_weighted function only checks that such an attribute exists. Your algorithm might be turned into class that incrementally update MST while new links added and dropping off rest of edges that isn't improving MST.

How would you alter Prim's algorithm to find the minimum spanning tree subject to the condition that {u, v} is in the tree. The weight of an edge is often referred to as the “cost” of the edge. An undirected graph is just a graph without arrows, just nodes and edges, precisely like what you provided. The value `pr' is the probability of there being an edge ; it controls the sparseness of the graph and on average there will be pr*|V|*(|V|-1) edges: (c) How would you generalize this idea?
