When I search from GAMS I saw the expression below;

Creation of the lst file can be suppressed by setting output to NUL under Windows

How can I do this?

Thanks..

Is it possible not to create lst file while running gams?
Because my lst file is really huge and for that reason, my computer has memory problems and stops running gams
I do not need a lst file

Thank you Fred, in fact I just fixed my problem.

In my code at somewhere there was OPTCR=0; I could not recognize, for that reason even I was defining it as 0.05 at the beginning of the code it was taking as 0.

Now it is ok, thanks for your reply

Hello Kubra, how many shifts do you have? how many operators will you assign to a single shift? you can not model your problem correctly without this information maybe you can determine an average experience level to each shift and make your goal not to deviate from this average experience level.

Hello, I want CPLEX to stop when an integer feasible solution that has been proved to be within 5% of optimality. For this, I am making OPTIONS OPTCR=0.05; After the time limit I set i.e. RESLIM=3600, I check the relative gap and see that it is i.e. 0.00085. In fact I want it to stop when the relati...

It works just as I need.

Thank you very much for your time.

Dear Renger, I am really very glad for your help. Thank you for the code, it works but unfortunately I recognized that I skipped to explain sth. In each iteration I am trying to keep the sets updated. For example is /3,5,7/ ib /1,2,4,6,8,9,10/ in the first iteration I got is /1,5,7/ ib /3,2,4,6,8,9,...

Hi Renger, Thank u very much for replying. Let me explain what I want to do with an example Sets i nodes /1*10/ N1(i) /3,5,7/ N2(i) /1,2,4,6,8,9,10/ We can assume that this is a facility location problem and N1 is the set of nodes at which I locate the facilities. I am trying to code an algorithm an...

Hello,

I have two different dynamic sets. I have iterations and in each iteration what I want to do is to choose one of the elements of each of the sets randomly and exchange them. How can I do this with Gams? I will be glad for your help, thanks

Hello,

Cplex automatically creates cuts and there are options for these cuts as -1.do not generate, 0.automatic, 1.moderate and 2.aggressive for cut generation.
When I am using the solver cplex in gams, how can I set these options in Gams?

Thank you for your help
