示例1: BreedWith

bool parentsHaveSameFitness = this->GetOrCalculateFitness() == partner.GetOrCalculateFitness();
Organism* dominantParent = nullptr;

dominantParent = rand() % 2 == 0 ? this : &partner;
}
else {
dominantParent = this->GetOrCalculateFitness() > partner.GetOrCalculateFitness() ? this : &partner;
}
Genome childGenome(dominantParent->GetGenome());
size_t sizeOfSmallerParent = min(this->GetGenome().GetGeneCount(), partner.GetGenome().GetGeneCount());
auto & partnerGenome = partner.GetGenome();
auto AreMarkingsSameAt = [&](size_t i) {
return childGenome[i].historicalMarking == partnerGenome[i].historicalMarking;
};
for (size_t i = 0U; i < sizeOfSmallerParent && AreMarkingsSameAt(i); ++i) {
if (rand() % 2 == 0) {
childGenome[i].weight = partnerGenome[i].weight;
}
}
NeuralNetwork child(move(childGenome), true);
// It may look ineffective to return this by value, accessing the copy constructor
// But don't worry, RVO will take care of this.
// If your compiler doesn't optimize this, I'd recommend using what you'd call an "out parameter" in C#
return child;
