I'm sure you'll have plenty nice - and entertaining - discussions! ;-)

So FWIW:
Your colleague likely complains that the schedule your program generates 
is not *fair*. You in turn claim it to be *random*. And since both of 
you are probably right there's little chance you'll eventually come to a 
satisfactory conclusion.

Taking for granted that my understanding of fairness is compatible with 
yours (and your colleague's) then fairness and randomness are incompatible.

YC explained this in more detail already.

So, if you want happy colleagues make it fair, not random.

Cheers,
Thomas
