示例1: diversifyPopulation
vector<int*> diversifyPopulation(vector<pdi>& costHeap, vector<int*> population, int numKeep, int numNew, DataFrame dataFrame, vector<int>* conflictGraph) {
vector<int*> newPopulation;
double fitness;
int id;
//vector<pdi> costHeapAux;
//make_heap(costHeapAux.begin(), costHeapAux.end(), smallerOp());
for(int i = 0; i < numKeep; i++) {
fitness = costHeap.front().first;
id = costHeap.front().second;
//costHeapAux.push_back(pdi(fitness, i));
//push_heap(costHeapAux.begin(), costHeapAux.end(), smallerOp());
pop_heap(costHeap.begin(), costHeap.end(), smallerOp());
costHeap.pop_back();
newPopulation.push_back(population[id]);
}
vector<int*> randomIndividuals = getPopulation(dataFrame.getInstance(), numNew);
for(int i = 0; i < randomIndividuals.size(); i++) {
KCenterSolver* ind = createSolver(dataFrame, randomIndividuals[i]);
ind->localSearch(conflictGraph);
newPopulation.push_back(ind->getSolution());
//costHeapAux.push_back(pdi(ind->getCost(), numKeep+i));
//push_heap(costHeapAux.begin(), costHeapAux.end(), smallerOp());

}
//vector<pdi>(costHeap).swap(costHeap);
//costHeap = costHeapAux;
