Question 1Russell and Norvig define rational agents as follows:For each possible percept sequence, a rational agent should select anaction that is expected to maximise its performance measure, given theevidence provided by the percept sequence and whatever built-inknowledge the agent has.Answer subquestions a), b) and c) with reference to the example applicationslisted below, justifying your answers:A. A ‘light show’ agent that accompanies a live musical performanceby flashing different coloured lights according to the pitch, volumeand timbre of the sounds.B. A ‘virtual mechanic’ that assists a car owner in diagnosing faultsand advising how to fix them or whether to call in a professional.C. A healthcare assistant that attends to a hospital patient by e.g.providing medication at appropriate times, carrying out routine testssuch as blood pressure or temperature, and respondingappropriately to requests from the patient.a) For each application A, B and Ci. Explain what type of agent would be most appropriate:• Simple reflex agent• Model-based reflex agent• Goal-based agent or• Utility-based agent.[4 marks]ii. Explain what kinds of actions the agent would need to executeand what kinds of percepts are likely to be available, andpropose a performance measure.[6 marks]b) For each application A, B and C, explain whether the agent’senvironment is:• deterministic or stochastic• fully or partially observable• static or dynamic• single or multi-agent.[8 marks]Page 3 of 10c) For each application A, B and C, classify the agent according to thefollowing dimensions in Poole and Mackworth’s design space:• modularity: flat, modular or hierarchical• planning horizon: non-planning agent or one with afinite, indefinite or infinite horizon?[7 mark

Rational decision making is characterised by making value-maximising choices that:Group of answer choicesrequire maturity.require high intelligence.have limited choices.are consistent.

Rational decision making is characterised by making value-maximising choices that:

The rational decision-making model focuses on using logical steps to come to the best solution possible. This often involves analyzing multiple solutions at once to choose the one that offers the best quality outcome.
