The goal in RL is usually described as that of learning a policy for a Markov Decision Process (MDP) that maximizes some objective function, such as the expected discounted sum of rewards. An MDP is characterized by a set of states S, a set of actions A, a transition function P and a reward function R. WebMar 13, 2024 · For example, if a security offers a series of cash flows with an NPV of $50,000 and an investor pays exactly $50,000 for it, then the investor’s NPV is $0. It means they will earn whatever the discount rate is on the security. Ideally, an investor would pay less than $50,000 and therefore earn an IRR that’s greater than the discount rate. dickies hanford ca
