Selection 
Submitted by Will on Thu, 2006-12-14 10:03

I'm unclear on what the selection rules mean;
1. I understand random
2. Fitness proportional: Does this mean genotypes with the best fitness are
selected for mutation/crossover?
3. Tournaments: Don't understand this.

Thanks,

Will

chance of selection proportional to fitness.

from k randomly chosen participants, the one with the
highest fitness gets selected.
