Johan - please post a reference to your above code. Is it from the File Exchange (possibly from https://www.mathworks.com/matlabcentral/fileexchange/52856-binary-and-real-coded-genetic-algorithms) or from the Optimization Toolbox? At a glance, it looks like the first type will produce two children whereas the second type will just produce one child (or have you neglected to add the second equation?). Note how if we rewrite it, we get
y'= (1 + alpha)*x2 - alpha*x1;
Depending upon what alpha is, it would seem that x2 is being weighted "more" than x1...and seems to be incorrectly weighted. Please include a reference to this equation.
