To be able to solve models in GAMS MIRO, GAMS 30.2 or later is required. You can download the latest GAMS version here.
Download & installation
Install GAMS MIRO Desktop
Note:
GAMS MIRO Desktop itself is open source software. In order for GAMS to interact with MIRO, the MIRO connector is required, which is included in the GAMS system from GAMS version 30.2. Without a valid license, the connector has limitations on the number of indexed symbols that can be communicated with MIRO. A maximum of 10 indexed symbols can be included in $on/offExternalInput and $on/offExternalOutput.
Please check the release notes.

Installation
- In case a current R version (4.0 or later) is not yet installed on your system, you need to do this first. You can download R here.
-
For MIRO to work, compilers as well as the system
libraries libpng and libcurl need to be installed.
On Debian / Ubuntu you need
libcurl4-gnutls-dev and libpng-dev, on
Fedora use libcurl-devel and
libpng-devel. For example, to install both
libraries on Ubuntu, run:
> sudo apt install libcurl4-gnutls-dev libpng-devIf there are no compilers installed on your system yet, we recommend installing build tools via: > sudo apt install build-essential on Ubuntu or: > sudo dnf groupinstall "Development Tools" on Fedora.
- The first time you launch the GAMS MIRO AppImage, some R packages need to be installed. They are installed either at the R installation path: rPath/miro-library or in the user's home directory ($XDG_CONFIG_HOME/miro-library or ~/.config/miro-library) depending on whether MIRO was installed for all users or only for the current user. You will be guided through this installation process.
GAMS MIRO workspace
The workspace is the place where deployed apps are stored and cached and logs are written. The MIRO database with all user scenarios is also located there. Furthermore all user settings and additional R packages are kept in the workspace.
On all platforms, the MIRO workspace is located at ~/.miro. On MacOS and Linux, ~ is resolved to: $HOME, on Windows to %USERPROFILE%.
Uninstall GAMS MIRO
To uninstall the software, please follow the default procedure of your operating system. The uninstaller only deletes the data in the directory where GAMS MIRO was installed. On Windows you will be asked if you also want to permanently delete the MIRO database with all your settings. This refers to data in the MIRO workspace. If you agree, the entire directory will be deleted. On both MacOS and Linux systems, the MIRO workspace is not deleted. To remove the data permanently, you have to do this manually.
Demo applications
We provide some GAMS MIRO demo applications. You can use these to get to know some of MIRO's basic features. To run the sample applications, you must first extract them. More about this here.
Note:
A well-known model from the GAMS model library is called trnsport. One of the MIRO demo models is based on this model and has been titled transport to avoid two models of the same name.
GAMS MIRO Server
Like GAMS MIRO Desktop, GAMS MIRO Server is open source software. However, the setup requires the use of GAMS Engine for the model calculations, which must be purchased separately.
Detailed installation instructions and further information on administrative aspects can be found here.
