Re: Is it possible to solve bi-objective model directly in GAMS?
Dear Steve,
If you want the truth, I'm just looking for a good solution And nothing special in my mind.
Thanks so much!

Is it possible to solve bi-objective model directly in GAMS?
Hi all,
Is there any command that can solve multi objective model directly? I mean, without using weighted sum or epsilon constraint methods, can we solve multi objective model in gams?
Many thanks!

Created a loop including CSVs
Hi all,
Is there any way to refer to the CSV files in a loop?
All my files have systematic names: file1.csv, file2.csv etc. How do I create a loop including all the files?
I am looking for something like this:
set j /1*10/
loop(j,
$include "filej.csv")
How do I go about it?
