These exercises are intended to stimulate discussion, and some might be set as term projects.
Alternatively, preliminary attempts can be made now, and these attempts can be reviewed
after the completion of the book.
1.1 Define in your own words: (a) intelligence, (b) artificial intelligence, (c) agent, (d)
rationality, (e) logical reasoning.
1.2 Read Turing’s original paper on AI (Turing, 1950). In the paper, he discusses several
objections to his proposed enterprise and his test for intelligence. Which objections still carry
weight? Are his refutations valid? Can you think of new objections arising from developments
since he wrote the paper? In the paper, he predicts that, by the year 2000, a computer
will have a 30% chance of passing a five-minute Turing Test with an unskilled interrogator.
What chance do you think a computer would have today? In another 50 years?
1.3 Are reflex actions (such as flinching from a hot stove) rational? Are they intelligent?
1.4 Suppose we extend Evans’s ANALOGY program so that it can score 200 on a standard
IQ test. Would we then have a program more intelligent than a human? Explain.
1.5 The neural structure of the sea slug Aplysia has been widely studied (first by Nobel
Laureate Eric Kandel) because it has only about 20,000 neurons, most of them large and
easily manipulated. Assuming that the cycle time for an Aplysia neuron is roughly the same
as for a human neuron, how does the computational power, in terms of memory updates per
second, compare with the high-end computer described in Figure 1.3?
