Does anyone know how to put an optimization program inside the loop in CPLEX solver and run the optimization program several times for different parameters?
Hi Nicolas,
Thanks for your answer. I used OPL script language and have *.mod and *.dat. If you have an simple example for this matter in cplex, I will be grateful .
regards
Hi Nicolas
I am very grateful for your useful information.
good luck
Assuming that you want to analyze the change of the parameter 'Beta' on the objective function 'Zobj', see the code below.
-----------------------------------------------------------
Main body of your GAMS code
...
set iter /iter1*iter5/;
parameter Beta_test(iter)
/iter1 0
iter2 0.2
iter3 0.5
iter4 0.8
iter5 1/;
parameter Ztest(iter);
...
loop(iter,
Beta = Beta_test(iter);
solve your_model using mip min Zobj;
Ztest(iter) = Zobj.l;
);
display Ztest;

Hi morteza,
Thanks for your answer. I solved my problem in cplex with "main".

Nicolas Dupin can I still use this method if I'm using CPLEX solver on MATLAB
Hi Nicolas Dupin,
I advise you to contact: Alex Fleischer (IBM Ilog Cplex Optimization Technical Account Manager) via Linkedin or here researchgate.
Hi Sorayya,
Could you please share how you solved your problem with 'main block'?
I have the same problem, can not change a parameter value and put it in a loop.
Thanks in advance.
Hi Bursa,
Sorry for delay in reply. I sent you 2 files that you can learn how use a "main block".
