Hello, I don't know how I should implement the first de jong function: f(x)=Sum((x_i)^2) where x is a Vector with n dimensions and x_i is the value of the i-th Dimension. i.e. all Values of the Vector are squared and added. My problem is that I don't know how many Dimensions there are, so I can't define the borders of the SUM function. thanks in advance for help Stefan
