. Give a PEAS description of each of the following task environments. a. A simple thermostat that turns on a heater when the temperature is at least 3 degrees below the setting, and turns off a heater when the temperature is at least 3 degrees above the setting. b. A route recommendation system which computes and suggests the best route to reach a destination. c. A group of ants searching for the shortest path from their nest to food sources. d. A computer program that given an image of a fingerprint can find the best match in a database of criminal fingerprints. 2. Characterize each task environment in problem 1 above in terms of the following properties: a. Single- or multi- agent. b. Deterministic or stochastic. c. Sequential or episodic. d. Static or dynamic. e. Discrete or continuous. f. Fully- or partially- observable. 2. Characterize each task in Problem 1 as an instance of a simple reflex agent, a modelbased agent, goal-based agent, utility-based or a learning agent?
