Fitness and Selection
- Fitness proportionate selection:
\[ \Pr(h_{i}) = \frac{Fitness(h_{i})}{\sum_{j=1}^{p} Fitness(h_{j})}
\] ... can lead to crowding (aka inbreeding).
- Tournament selection Pick $h_1, h_2$ at random
with uniform probability and then, with probability $p$,
select the more fit.
- Rank selection Sort all hypotheses by fitness
then the probability of selection is proportional to rank.
