Textbook Question
Chapter 2, Problem 1E
Suppose that the performance measure is concerned with just the first T time steps of the environment and ignores everything thereafter. Show that a rational agent’s action may depend not just on the state of the environment but also on the time step it has reached.
Expert Solution & Answer
Explanation of Solution
Performance measure
- It tests the student’s understanding of environment, rational actions, and performance measures.
- Any sequential environment in which rewards may take time to arrive will work.
- This is because it can be arranged for the reward to be over the horizon.
- The environment state can include a clock and the action will depend on the clock as well as on the non-clock part of the state.
