I am using C++ concert technology to model Math Programming. But, it was showing some error.
Firstly, I am new to CPLEX, so I need sometime to develop my knowledge.
Secondly, it was showing "out of memory error". When I was running the model, it occupied all the memory. The model was using a binary variable xkpt , where k=resource, p =project and t=time. The model is working fine for k=3, p = 3, t =3; i.e., for 3*3*3=27 decision variables. But, it was showing "out of memory " error only for 5*3*4= 60 variables. I asked my Guide and as well as I searched in the forums. Both of the sources had suggested that the memory should be OK for thousand of variables. So, there exists some discrepancies which I could not find.
Please help me.
