I am newbie to the GAMS and I am currently using existing code developed by some other researcher. When I am calibrating the model for my data, I am getting a solver error. I am using Ipopt as a NLP solver and the error I am encountering is
Converged to a point of local infeasibility. Problem may be infeasible
I do not have any idea to solve this. I would be grateful it someone advice me on this.
