Lorenz Attractor Periodic Orbits
The butterfly-like Lorenz attractor is a simplified model of two-dimensional convective fluid flow and is one of the best known images of chaos. Embedded in this attractor are unstable periodic orbits described by Viswanath and this model computes a number of these orbits. Each periodic orbit is classified by the number of times the trajectory orbits the A and B fixed points before it repeats. Note that because the attractor is chaotic and because of numerical errors and the finite precision of

Linear Congruent Number Generator
The Linear Congruent Number Generator Model The method generates a sequence of integers xi over the interval [0, m-1] by the recurrence relation x[i+1] = (ax[i]+c) mod m Where the modulus m is greater than zero, the multiplier a is greater than zero and less than m, and the increment c is greater than zero and less than m.Â All numbers are integers and all arithmetic is integer arithmetic.Â The initial value x0 is known as the seed.Â

Multiple Coin Toss Model
The EJS Multiple Coin Toss model displays the result of the flipping of N coins. The result of each set of coin flips is shown by the image of the pennies on the screen and the complete results of the tossing experiment is shown on a graph of the cumulative probability of heads. The number of coins flipped, N, and change the "fairness" of the coin by setting the probability of a "heads" result, p, can be set via text boxes.
