 +//I have tried in vain for the past few days trying to fix this problem. Could you suggest what might be wrong?// ​

 +This is not always bad, it means that MINOS is stuck in a local point without being able to establish local optimality. This may very well be the point you want to add up. It is difficult to to say more without having a look at the model. Sometimes it helps to restart the model a few time using other starting levels for some variables .

 +Another way is to switch algorithm to another NLP code or a global optimization code.
