Question

2.1 What is the difference between a performance measure and a utility function?

2.3 Choose a domain that you are familiar with, and write a PAGE description of an agent
for the environment. Characterize the environment as being accessible, deterministic, episodic,
static, and continuous or not. What agent architecture is best for this domain?

2.4 While driving, which is the best policy?
a. Always put your directional blinker on before turning,
b. Never use your blinker,
c. Look in your mirrors and use your blinker only if you observe a car that can observe you?
What kind of reasoning did you need to do to arrive at this policy (logical, goal-based, or utilitybased)?
What kind of agent design is necessary to carry out the policy (reflex, goal-based, or
utility-based)?

Answer 1

2.1-

a. A Performance Measure is used to evaluate the behavior of the agent in anvironment.

b. A Utility Function used is used by an agent itself to evaluate how desirable states are.

c. The Utility function may not be the same as the performance measure. An agent may have no explicit utility function at all whereas there is always a performance measure.

A Performance measure is objective and can include information unavailable to the agent. A utility function only includes information available to the agent and is an estimate of the performance measure.

2.3-

a. Deterministic and Staticnes are the agent for the environment.

b. Discreteness(discrete or continuous ):- A discrete environment has fixed location or time intervals. A continuous environment could be measured quantitatively to any level of precision.

In each case, the job of the AI is easier if the first of the two options is best in mention a option. That is, an AI has a much more difficult job if it works in an environment that is stochastic, dynamic, partially observable, multi agent, unknown, sequential & continuous.

2.4-

a. The best policy is A. Logical reasoning based on if everyone takes that action the world will work in a desirable way. Reflex agent can carry out this policy.
