课程：Computing chaos.
Chaotic behaviour occurs when a system (described by a simple equation)
exhibits behaviour which is unpredictable in the long term. A classic
example of a chaotic system is the weather. How chaotic a particular system
is can be measured using a quantity called the Lyapunov exponent. The
mathematics involved is not difficult (though the student should ideally
have studied maths to A level) and the computer programming is not difficult
either! However the calculations are very CPU intensive and the student
will be required to come up with creative ways to distribute the
calculations across a number of machines.
最低要求：能使用standard language (such as C) 或者matlab画出logistic map
例子如下：(matlab)
a = (0:0.01:4)';
iterations_per_value = 500;
y = zeros(length(a), iterations_per_value);
y0 = 0.2;
y(:,1) = a.*y0*(1-y0);
for i = 1:iterations_per_value-1
y(:,i+1) = a.*y(:,i).*(1-y(:,i));
end
plot(a, y, '.', 'MarkerSize', 1);
