1. Consider the following digraph, where we have a link (xi, xj) for each I s i < j s n-#(nodes)-5. We have seen such a digraph before when we let x, represent the integer i and the links represent"" relationship between integers. Because there is no cycle in this digraph, such digraphs are called acyclic digraph (in short. DAG directed acyclic graph). Also, because it has the maximum number of links possible for a DAG, it is called a...

Problem 5.10.10 Suppose you have n suitcases and suitcase i holds Xi dollars where X1, X2, …, Xn are iid continuous uniform (0, m) random variables. (Think of a number like one million for the symbol m.) Unfortunately, you don’t know Xi until you open suitcase i. Suppose you can open the suitcases one by one, starting with suitcase n and going down to suitcase 1. After opening suitcase i, you can either accept or reject Xi dollars. If...
