[Numpy-discussion] minimize Algorithmen Problem with boundarys

2014-06-06 Thread Vertigo
Hello everybody, i have a Problem, with three minimize Algorithmen in scipy. I need Algorithmen to support a minimize Algorithmen with boundarys. My favorits are the 'l-bfgs-b', 'slsqp' and 'tnc' but all of them give a failure meanwhile solve my problem. By call the methode SLSQP it give me fail
