Hey Lutz,
Thanks your suggestion! That's indeed a clever and simple solution, though I have to check if it breaks other parts of the script since it changes the include file structure!
Thanks,
Christoph

Enable $show / $showVariables from Command Line
Hi :wave: I'm parsing the results of the $show command, specifically $showVariables (aka the compile time variable list) using a script. Right now, the script relies on the $show command being present at the end of an input GAMS file, otherwise the compile time variable list would obviously not be p...

GDXIN produces compilation error in dump file with onEmpty
Hi there, I'm (once again) running a model with the command line parameter `dumpOpt=11` in order to generate a single GAMS file containing all includes and data. However, using GDXIN with empty empty data statements seem to create a compilation error in the .dmp file. Consider the following minimum ...

Data storytelling in operations research
Hey there :) I'd like to use the opportunity to showcase a piece we have done regarding interactive "data-story" notebooks using GAMS. An Introduction to operations research in Observables https://user-images.githubusercontent.com/20703207/87766667-d1ee1480-c819-11ea-9d1c-c8db46ffb17a.png ...

GDXIN produces compilation error in dump file
Hi there, I'm running a model with the command line parameter `dumpOpt=11` in order to generate a single GAMS file containing all includes and data. However, using $GDXIN with 0 level elements seems to create a compilation error in the .dmp file: Simplified (reproducible) problem (which compiles fin...

Re: Writing model tests - best practices
Thanks Steve and Renger for your replies, So again a short note about our current procedure: We don't do the tests manually anymore, as we wrote an R-script that automates the process: 1) On every SVN update, a post-commit hook on the SVN server runs the R-script, which in turn runs the GAMS batch f...

Writing model tests - best practices
Here at our institute, we work on a couple of (larger scale) economics related GAMS models. Different teams, involved in different projects make adaptations to the models in order to answer their specific research questions. The models are equipped with a Graphical User Interface (GUI), and are vers...

Re: CPLEX does not find true optimum despite optcr=0
Thanks @ameeraus for the reply and the elegant solution to my problem. As you might have guessed, I totally oversaw that my .fx was actually resetting the lower bound of the variable. If I would have actually set a lower bound of 1 (instead of fixing it), I would have received a matrix error stating...
