1Well, if the function to be optimized is also linear. But, at the end, these are computer programs. Computers hate us. See "I Have No Mouth and I Must Scream" by Harlan Ellison. – 2012-05-23

0What nonlinear solver and what linear solver are you using? What optimality criteria are used by either? – 2012-05-24
