我有一个浮点异常,我不知道为什么.
代码是这样的:
void calcola_fitness(){
vector<double> fitness;
int n=nodes.size();
int e=edges.size();
int dim=feasibility.size();
int feas=(feasibility[dim-1])*100;
int narchi=numarchicoll[dim-1]/e;
int numero_nodi=freePathNode.size()/n;
double dist_start_goal=node_dist(0,1);
int i,f,t;
double pathlenght=0;
int siize=freePathNode.size();
for(i=0;i!=siize-1; i++){
f=freePathNode[i].getIndex();
i++;
t=freePathNode[i].getIndex();
i--;
pathlenght=pathlenght+node_dist(f,t);
}
double pathlenghtnorm=pathlenght/10*dist_start_goal;
double fit=((double)numero_nodi+pathlenghtnorm+(double)narchi)*((double)feas);
fitness.push_back(fit);
}
有人能帮助我吗？有什么问题？我可以解决这个问题吗？非常感谢你
