Second-Order Random Walk) Given the following directed graph. 4 Suppose the node-to-node transition probability matrix is nodes 0.4 0 0 0 0.7 0 0.6 0 0 0 0.3 0 Suppose the random surfer starts from node 1 at time point 0 and follows the first-order random walk. Then, at time point 1, the node probability distribution is nodes Prob. dist. Then, at time point 2, the node probability distribution is nodes 4 Prob. dist. Then, at time point 3, the node probability distribution is nodes Prob. dist
