Re: GA parameters

Hello Rok,

Thank you for your posts.

My fitness function is not an analytical function. I am doing turbomachinery
aerodynamic shape optimization.
Fitness is the inverse of the penalties we give to the performance of a,
say, compressor impeller.
This can be a sum of its squared differences between the desired (qd) and
obtained efficiency (q), desired
and obtained mass flow etc. The solution is coming from fluid mechanics
Navier-Stokes equations.

Like p=Sum(qd**2-q**2) where q is say effciciency and massflow in the above
example.
fitness=1/p (Obviously we make sure p>0)

It is a very nonlinear and possibly also noisy because of the effects of
grid etc.

Of course I can even send you some papers if I am making any sense to you
here.

Again many thanks for your time,

Regards
Zuheyr
