Markov decision processes 1. (3pts) Consider the sample MDP from the class notes (section 7.4.1). Currently, an overhaul of the machine in state 2 costs $4,000. Leaving everything else the same, how much would the overhaul cost need to increase (to the nearest $100 ) before overhauling in state 2 is no longer part of the optimal policy?
