示例1: Elitism
void
Strategies::RankSelection( Population &pop ) {
/* Take care of elitism first */
Elitism( pop );
/* Create roullette wheel */
float max = 0;
float min = 999999999999999999;
float sum = 0;
float roulette[pop.GetAdults().size()];
/* Find min and max */
for ( unsigned int i = 0 ; i < pop.GetAdults().size() ; i++ ) {
if ( max < pop.GetAdults().at(i).GetFitness() ) max = pop.GetAdults().at(i).GetFitness();
if ( min > pop.GetAdults().at(i).GetFitness() ) min = pop.GetAdults().at(i).GetFitness();
}
max = pop.GetAdults().back().GetFitness();
min = pop.GetAdults().at(0).GetFitness();
roulette[0]=0;
for ( unsigned int i = 1 ; i < pop.GetAdults().size() ; i++ ) {
roulette[i] = roulette[i-1] + min+(max-min)*(i - 1) / (pop.GetAdults().size() - 1);
}
sum = roulette[pop.GetAdults().size()-1] + max;
Select( pop, roulette, pop.GetAdults().size(), sum );
}示例2: sort
void
Strategies::Elitism( Population &pop ) {
unsigned int elitism = pop.GetElitism();
if (elitism > 0) {
sort(pop.GetAdults().begin(), pop.GetAdults().end(), IndividualSort);
for (unsigned int i = 0; i<elitism; i++) {
pop.GetChildren().push_back(pop.GetAdults().at(i));
}
}
}示例3: while
void
Strategies::OverProduction( Population &pop ) {
/* All adults die, children fight to become adults */
pop.GetAdults().clear();
int num;
while ( pop.GetAdults().size() < pop.GetAdultsSize() ) {
num = rand() % pop.GetChildren().size();
pop.GetAdults().push_back( pop.GetChildren().at( num ) );
pop.GetChildren().erase( pop.GetChildren().begin()+num );
}
/* Clear children */
pop.GetChildren().clear();
}
