[25pts] [non-programming problem] When we discuss the dynamic programming methods, we provide two value iteration algorithms. One of them is to directly estimate the optimal state value function. Once that function is accurately estimated, a greedy action policy with respect to this function gives the optimal action policy. The in-place value iteration algorithm is given as follows: Value Iteration, for estimating Algorithm parameter: a small threshold >0 determining accuracy of estimation Initialize V(s), for all sS+, arbitrarily except that V( terminal )=0 Loop: {0LoopforeachsS:vV(s)V(s)maxas,rp(s,rs,a)[r+V(s)]max(,vV(s))until
