Exercise 1.1.#DEFA dt



Define in your own words: (a) intelligence, (b) artificial intelligence, (c) agent, (d) ra-

tionality, (e) logical reasoning.

a. Dictionary definitions of intelligence talk about “the capacity to acquire and apply kno dt dt dt dt dt dt dt dt dt dt dt dt



wledge” or “the faculty of thought and reason” or “the ability to comprehend and profit
dt dt dt dt dt dt dt dt dt dt dt dt dt dt



from experience.” These are all reasonable answers, but if we want something quantif

iable we would use something like “the ability to act successfully across a wide range of

objectives in complex environments.” dt dt dt



b. We define artificial intelligence as the study and construction of agent programs that

perform well in a given class of environments, for a given agent architecture; they do t

c. We define an agent as an entity that takes action in response to percepts from an envi-

d. We define rationality as the property of a system which does the “right thing” given w

e. We define logical reasoning as the a process of deriving new sentences from old, such th
