The server presents to you a parametric curve, with an
animation showing how a point on the curve varies with the variation of
the parameter *t*. And you have to find two functions *F*(*t*), *G*(*t*)
such that the corresponding parametric curve is as close as possible to that
of the server, point by point. You can try several times, and your best reply
will be taken into account to compute a score attributed to you. The computation
of the score is based on the difference between the curve of the server and
that of yours.

You will be free to use any usual functions: polynomial, rational, exponential, logarithmic, trigonometric or inverse, hyperbolic or inverse, etc. And you will need to compose these functions in a most efficient possible way, as your function must be limited in its length.
