示例1: CalculateAngleToDepot
private static double CalculateAngleToDepot(IVRPProblemInstance instance, int city) {
double dx = instance.GetCoordinates(0)[0];
double dy = instance.GetCoordinates(0)[1];
double cx = instance.GetCoordinates(city)[0];
double cy = instance.GetCoordinates(city)[1];
double alpha = Math.Atan((cx - dx) / (dy - cy)) * (180.0 / Math.PI);
if (cx > dx && cy > dy)
alpha = (90.0 + alpha) + 90.0;
else if (cx < dx && cy > dy)
alpha = alpha + 180.0;
else if (cx < dx && cy < dy)
alpha = (90.0 + alpha) + 270.0;
return alpha;

private double CalculateCentroidDistance(Tour t1, Tour t2, IVRPProblemInstance instance) {
double xSum = 0;
double ySum = 0;
double c1X, c1Y, c2X, c2Y;
for (int i = 0; i < t1.Stops.Count; i++) {
