Fitness proportionate selection lower fitness code example
Example: roulette algorithm genetic algorithm
for all members of population
sum += fitness of this individual
end for
for all members of population
probability = sum of probabilities + (fitness / sum)
sum of probabilities += probability
end for
loop until new population is full
do this twice
number = Random between 0 and 1
for all members of population
if number > probability but less than next probability
then you have been selected
end for
end
create offspring
end loop
