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.
Dual infeasible due to empty column 'eta0'.
Presolve time = 0.00 sec.
CPLEX Error 1217: No solution exists.
Problem is integer infeasible.
