Hi Troels, You should note that the minimise.execute user function does not allow the log-barrier or the method of multipliers algorithm to be chosen. This is instead via the constraint flag. Therefore this logic will not work. The choice of constraint algorithm occurs in the back-end code, as it is uses dead simple logic:
No gradients implemented = log-barrier. Gradients implemented = Method of Multipliers. You cannot mix these as the Method of Multipliers absolutely requires the gradient, and the log-barrier method currently does not implement its gradient.
