For quite a while we have been providing the option to play around with GAMS in Jupyter notebooks in a hosted environment at https://jupyterhub.gams.com/. That place is still a good resource for getting started and provides a few examples of how to use GAMS in this environment. We have received a lot of requests to make this available for local installation, and we listened.
TIMES is a sophisticated energy model generator implemented in GAMS. It has been published under an open source license in 2019. Recently, GAMS joined forces with experienced TIMES users to develop an open-source TIMES/MIRO App that serves as a frontend to the TIMES model. This was made possible by new features in GAMS MIRO 1.1
We’ve got some new links from Pyomo and JuMP to GAMS, which allow efficient interfacing of GAMS with your Pyomo or JuMP models.
With schools and universities shutting down globally due to the ongoing pandemic, some university students using GAMS in their projects have been locked out of computer labs.
We are proud to announce the release candidate for GAMS MIRO 1.0.
Given the crucial role power distribution plays for the economy, and the challenges posed by renewable energy and increasing demand for electricity, ARPA-E is running the Grid Optimization Competition, which challenges participating teams to develop and test power system optimization and control algorithms on a range of different synthetic and real network models.
Some of you might have noticed that coincident with releasing GAMS 30.1, we have introduced some changes to our licensing model [https://www.gams.com/latest/docs/UG_License.html]. Below we summarize what has changed. Demo We have changed the way we allow users to test GAMS (“demo mode”).
