Name: <name>Student Number: <student_number>(a) An agent that senses only partial information about the state cannot be perfectly rational.This statement is False. Reason: The agent that sense partial information can be rational agent. Let’s take the example of street Cameras installed for surveillances. As expected mounted street camera can capture the all the images. So, it is rational agent. Here, the performance measure of the agent is the quality of the images captured. It does not sense other information like smell. So, with the partial information, Camera is reasonable and sensible to make the good sense of judgement based on the partial information. Hence it is proved, it is not necessary for perfectly rational agent to sense complete information.Let’s take another example of time bucket. Sometime the performance is measure for particular time span says for first T times. So, the agent can neglect everything after T time. Here agent is rational, but it is not sensing complete information. The performance is measured for the particular time span, not for complete time. Example, we can set the street signals that only works for the peak time traffic.(b) There exist task environments in which no pure reflex agent can behave rationally.This statement is True. Reason: First of all, we should consider two important percepts – current percept and previous percept. The decision can be taken based on either of two percepts or using both.Here, Pure agent is an agent which make the decision or react or take the action based on the current percept.
