Hello GAMS user,
I have a wierd issue when I try to solve the Mixed Complementarity Problem. In short, the problem is that during execution, the system tells me that the defxDev in the model is 'None'. However, when I define the model, I define the equation as:
defxDev(a).. -1 =N= 0;
I don't know what causes this kind of problem. Hope someone can tell me where I am wrong. I attached the detail .gms file here
