INTRODUCTION
Note that for many of the questions in this chapter, we give references where answers can be
found rather than writing them out—the full answers would be far too long.
1.1 What Is AI?
Exercise 1.1.#DEFA
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
knowledge” or “the faculty of thought and reason” or “the ability to comprehend and
profit from experience.” These are all reasonable answers, but if we want something
quantifiable, we would use something like “the ability to act successfully across a
wide range of objectives in complex environments.”
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
the right thing. An important part of that is dealing with the uncertainty of what the
current state is, what the outcome of possible actions might be, and what is it that we
really desire.
c. We define an agent as an entity that takes action in response to percepts from an envy-
ornament.
d. We define rationality as the property of a system which does the “right thing” given
what it knows. See Section 2.2 for a more complete discussion. The basic concept is
perfect rationality; Section ?? describes the impossibility of achieving perfect rational-
it and proposes an alternative definition.
e. We define logical reasoning as a process of deriving new sentences from old, such
that the new sentences are necessarily true if the old ones are true. (Notice that does not
refer to any specific syntax or formal language, but it does require a well-defined notion
of truth.)

objections to his proposed enterprise and his test for intelligence. Which objections still carry
