4. In class, it was shown that the optimal message passing problem reduce to a minimum spanning tree problem. In that reduction, the weight we of edge e is set to w= -In(1-pe), where p, is the failure probability of e. Show that the optimal message-passing problem can be solved by finding a minimum spanning tree in a graph whose edge weights are we=pe
