This problem has an interesting corollary.

Years ago, the BBC decided to introduce a new family show called
"Superstars" In this show, they tried to find the best sportsman in the UK
. They ran many programmes which featured six sporstmen against each
other and the winner went through to a final. Typically the sportsmen
could include boxers, runners, footballers, jockeys, cricketers, swimmers
There were several events such as a race, a swim but one event was lifting
weights. In each event the first second and third places got points and the
one with the biggest overall points won. With regards to this course, they
had a similar problem - faced with people of different weights and sizes
who is the best at lifting weights

. The difficulty of course is the word "best"

In modelling there are many words ( such as best, optimum ) which every
one understands but really are not clearly defined . One of the tasks of a
modeller is to think about such words.
