Challenge Problems
Push your limits with advanced challenges
Propose a complex scenario where an agent must decide between multiple actions with unknown rewards. Use the Bellman Equation to calculate the state values and determine the optimal action.
💡 Hint: Break down the problem: represent the states, possible actions, and their rewards clearly.
You have a grid-world agent that receives a reward of 10 for reaching the goal but incurs a penalty of 1 for each step taken. Formulate the Bellman Equation to derive the optimal path and explain how the discount factor influences the results.
💡 Hint: Consider how both immediate and future rewards need to be evaluated to engage the optimal path.
