Question 2: Consider a robot vacuum cleaner. What type of environment is this agent subjected to. Which type of agent can be more suitable for modelling such environment. Justify your answers with some explanation.
Solution: Agent type: Utility-based Agent
Explanation: The vacuum cleaner agent has the following functions: move left, right, back, front, and suck dirt from the floor. Here, the performance of the agent can be measured by how effectively and efficiently it can complete the task. A utility-based agent doesn’t only focus on the goal but also on the best way to reach that goal i.e minimize path cost and search cost.
