Deterministic Chaos

Tent Map

The Tent Map is one of the simplest nonlinear functions. It consists of two linear functions:

T(x) = s*x for x <= 1/2
T(x) = s*(1-x) for x >= 1/2

For small x, the Tent Map represents growth; for larger x decline, perhaps an effect of competition for limited resources.

Note the maximum value occurs at x = 1/2, and that maximum value is s/2.

We shall see the graph should stay inside the unit square. Consequently, we restrict the number s to the range,/P.

0 <= s <= 2.

We shall see that as s varies, the structure of the orbit x0, x1 = T(x0), x2 = T(x1), ... varies in a very complicated way, but not as complicated as that of the logistic map.

Nevertheless, the iterates of the tent map exhibit rich behavior, including chaos.
