Hello @fkarimi67,

Rastrigin function.

public class Rastrigin implements ISingleObjectiveFunction{

    public Rastrigin() {}

    @Override
    public double Compute(double[] values) {
        
        double sum = 0;
        for (int i = 0; i < values.length; i++) {
            sum += values[i]*values[i] - 10 * Math.cos(2*Math.PI*values[i]);
        }
        
        return 10 * values.length + sum;
        
    }
    
}

Now the main code below:

ISingleObjectiveFunction fun = new Rastrigin();

List<DoubleRange> boundConstraints = new ArrayList<>();
for (int i = 0; i < 30; i++) {
    boundConstraints.add(new DoubleRange(-5.12, 5.12));
}

IOptimization opt = new GreyWolfOptimizer(25, 1000);

double[] bestSolution = opt.Compute(fun, boundConstraints);
double error = opt.getError();

System.out.println(error);

Cheers !!!

Thank you In which part of the program I add code? Error no main classes found?

Hi, is this code correct?
