Oh, dear! I would not like to get fired immediately. So, we wrote a computer program in a hurry, using a random number generator giving Gaussian distributed numbers according to the bell curve to the left in the figure below. A cluster of points in two dimensions - where each pair of two Gaussian distributed parameters is represented by a point - is seen to the right.

The system functions of each randomly chosen system were calculated and compared with the requirements. In this way we got a population (generation) of about 1000 systems from which a certain fraction of approved systems was selected. For the next generation the centre of gravity of the Gaussian distribution was moved to the centre of gravity of the approved systems and this process was repeated for many generations.
