Problem 3: [20 points] Suppose that we model a social network with a graph, denoted by C::UEH, where VE:{1,H.,n} is the number of members 0' the social network, and E(:P7XI/, i.e., (Lj)E E if i has a link to j. We assime t at the graph is urdirected, in that if (Lj)E_E, then (i)E_E. We denote by Ag :he neighbour o:i, always including iitself, in the graph G, i.e., the set of nodes that i is connected to. Suppose tha: the number of individuals is larges, and that we cannot really get access to G, but that our objective is to create a ranking of the individuals in this network; we consider a random walk on this graph where 1 - _ Rf:{MIJEN; {) otherwise. 1.
