Dual infeasible due to empty column

Post by Bingo LI » 1 week ago

Hello all,
I am trying to solve a model using GAMS, and I am getting a problem: Dual infeasible due to empty column 'eta0'. What can I do to solve this problem.
The log of solving the problem is as follows, and the code can be attached if needed.
Many thanks.
