Superb!

After a little trial and error I finally made it work with your help. Great!

Thanks again to both of you!

Hello,

if I dont understand wrong,$ here is useful(dynamic sets):

sets I_A(I),I_B(I);

I_A(I)(x.l(I)eq 1)=yes;
I_B(I)(x.l(I)eq 0)=yes;

Is this right?

Hope it helps!

So what I will do is to use two GAMS files.

File 1 will calculate the initial solution and store it into a GDX file. That’s an easy one so far: execute_unload “results.gdx” x.L y.L

File 2 then should use the information stored.

Here is my setup: x and y are binary variables of Set I resp. J. The result is then x1=0, x2=0, x3=1, x4=0, x5=0, x6=1 (and for y accordingly).

In File two I have again set I, but then divide it into two subsets: I_A and I_B.

I_A contains all x that equal 1 and I_B contains all x that equal zero.

To load the file I assume it’s the command execute_load “results.gdx” x.L y.L (with sets I (for variable x) and J (for variable y) defined before in File 2)

How can I then split the loaded results into my subset?

Thanks again to all!

Usually ,I’ll use two gams file,each for a model and write and read the solution into an excel or txt file with $inlcude command.

all you need to do is click twice in the gamside .

Hope it’ll help!

Hi everyone!

Quick question: Is it possible to (automatically) use the solution of a GAMS model as initial solution to another GAMS model and run it at once?

I know how to include an initial solution in the model and how to run batches. But how can I link two GAMS files, so that the second one uses the solution of the first one as its starting point?

Could I even do that in one combined GAMS file?

Thanks for your support!
