I am trying to optimize function similar to the following: Minimize x1^2 - x2^2 - x3^2
st x1 < x2 x2 < x3 The constraint is that the variables should be monotonically increasing. Is there any package that implements Sequential Quadratic Programming with ability include these constraints??? Thanks you.
