The Computer Artist and Art Critic
J. C. Sprott
For decades, the generation of art by machines has fascinated both
and artists. In this chapter, I describe how modern computers can
and evaluate fractal patterns. The patterns are the products of
feedback loops, better known to mathematicians as iterated maps and
function systems. The computer solves the equations with random
of parameters and thereby produces an unlimited variety of patterns.
patterns can be characterized by numerical quantities known as the
exponent and the fractal dimension. In studies with human subjects,
found a correlation between these quantities and the aesthetic
of the patterns. This suggests that the computer can be taught to
fractal patterns that appeal to humans. I provide computer code and
of the patterns produced by this technique. I also discuss the
problem of using a computer to evaluate art produced by humans. The
of these methods holds unlimited promise.
