I have the following code for implementing bender’s decomposition. When I run the code I the loop doesn’t function properly as it seems the variables are fixed for some reason that I am not aware of. Please let me know how I should proceed with debugging.

Thank you.

The problem is solved now. The fixed variable problem occurs because the variables of each problem instance was not defined together with the eqautions.
