Multiple application domains

GAMA was developed with a very general approach and can be used for many application domains. GAMA is mostly present in applications domains like transport, urban planning, disaster response, epidemiology, analysis of multirobot systems, and the environment, with special emphasis on analyses that use GIS data.

High-level Agent-based language

GAML (GAma Modeling Language) is the dedicated language used in GAMA. It is an agent-based language, that provides the possibility to build a model with several paradigms of modeling. This high-level language was inspired by

User interface

Modelers may use many visual representations for the same model, in order to highlight a certain aspect of a simulation. These include 2D/3D displays, with basic control of lighting, textures, and cameras. Standard charts such as series plots may also be constructed.

Project examples

The developers maintain a community-sourced list of scientific projects that use GAMA. Some of the larger efforts include: * Hoan Kiem Air: Agent based modeling and simulation of the urban management on traffic and air pollution through tangible interface. * Proxymix: Visualization tool about the influence of spatial configuration on human collaboration. * CityScope Champs-Elysées: An interactive platform to improve decision-making related to the revitalization of the Champs Élysées. * ESCAPE: A Multi-modal Urban Traffic Agent-Based Framework to Study Individual Response to Catastrophic Events. * COMOKIT: Generic model of public policies to contain the spread of COVID-19 epidemics in a city, validated on the basis of different case studies.

Users

Several academic institutions teach modeling and simulation courses based on GAMA. It is taught in the Urban Simulation class at the Potsdam University of Applied Sciences, and at the University of Salzburg. It is also used and taught annually at the Multi-platform International Summer School on Agent-Based Modelling & Simulation
