Question: Repeat Exercise I for the case in which the location sensor is replaced with a "bump" sensor that detects the agent's attempts to move into an obstacle or to cross the boundaries of the environment. Suppose the bump sensor stops working; how should the agent behave?
Exercise I: Consider a modified version of the vacuum environment in Exercise II, in ,which the geography of the environment-its extent, boundaries, and obstacles-is unknown, as is the initial dirt configuration. (The agent can go Up and Down as well as Left and Right.)
a. Can a simple reflex agent be perfectly rational for this environment? Explain.
b. Can a simple reflex agent with a randomized agent function outperform a simple reflex agent? Design such an agent and measure its performance on several environments.
c. Can you design an environment in which your randomized agent will perform very poorly? Show your results.
d. Can a reflex agent with state outperform a simple reflex agent? Design such an agent and measure its performance on several environments. Can you design a rational agent of this type?
Exercise II: Implement a performance-measuring environment simulator for the vacuum-cleaner world depicted in Figure 2.2 and specified on page 36. Your implementation should be modular, so that the sensors, actuators, and environment characteristics (size, shape, dirt placement, etc.) can be changed easily.
