Minimum Spanning Trees
Consider an undirected graph, with nonnegative edge weights such that AAeinE. Suppose that you have computed a minimum
spanning tree for as well as the shortest paths to all nodes from a particular node Decrease the weights of all edges in the graph, such that
AAeinE.
a pts Does the MST of change under this weight adjustment? Either provide an example of a graph for which it does change, or prove that it
cannot change.
b pts Do the singlesource shortest paths from change? Either provide an example of a graph for which it does change, or prove that they cannot
change.
