This is where the problem starts, as we now have 11 parameters (eight for the shapes and
three for the weighting coefficients). We could of course simply cycle through every
possible value. Given, say, 100 possible values for each parameter, we then have to search
10
22
combinations of parameters which would be no problem given multithread computers
with Terrahertz processing speed achieved via optical interconnect, but that is not now.
Naturally, we can reduce the number of combinations by introducing constraints on the
relative size and position of the shapes, e.g. the circle should lie wholly within the ...
