Dear researchers
I have a GAMS file with Errors that I can not understand how to solve them,
actually this code has been written for bender decomposition algorithm,
It will be great helpful for me anybody could advise me about my errors.
my file has been attaced

Dear Iman,

That’s easy to implement. See the examples of following papers.

  1. Benders Decomposition










    Benders Decomposition
    -u(i) + v(j) - w(i,j) =l= 0; edummy.. dummy =e= 0; model modifiedsubproblem /modifiedsubobj, modifiedsubconstr, edummy/; * reduce output to listing file: modifiedsubproblem.solprint=2;
