    GAMA[3][4] (GIS Agent-based Modeling Architecture) is a simulation platform with a complete modelling and simulation integrated development environment (IDE) for writing and experimenting spatially explicit agent-based models.[5][6]

    About

    [edit | edit source]

    The GAMA Platform is agent-based modeling software that was originally (2007–2010) developed by the Vietnamese-French research team MSI (located at IFI, Hanoi, and part of the IRD - SU International Research Unit UMMISCO). It is now developed by an international consortium of academic and industrial partners led by UMMISCO Archived 2022-01-23 at the Wayback Machine, including INRAE, the University of Toulouse 1, the University of Rouen, the University of Orsay, the University of Can Tho, Vietnam, the National University of Hanoi, EDF R&D, CEA LISC, and MIT Media Lab.[6]

    GAMA was designed to allow domain experts without a programming background to model phenomena from their field of expertise.[7]

    The GAMA environment enables exploration of emergent phenomena. It comes with a models library including examples from several domains, such as economics, biology, physics, chemistry, psychology, and system dynamics.[8] The GAMA simulation panel allows exploration by modifying switches, sliders, choosers, inputs, and other user interface elements that the modeler chooses to make available.[9]

    Technical foundation

    [edit | edit source]

    GAMA Platform is free and open-source software, released under a GNU General Public License (GPL3).[10] It is written in Java and runs on the Java virtual machine (JVM).[11] All core components and extensions are written in Java, but end users do not need to work in Java at all if they use a published build of the platform; instead, they would write all models using GAML (described below).

    Multiple application domains

    [edit | edit source]

    GAMA was developed with a very general approach and can be used for many application domains.[5] GAMA is mostly present in applications domains like transport,[12][13][14][15][16] urban planning,[14][15][16] disaster response,[17] epidemiology,[18][19][20] analysis of multirobot systems,[21][22] and the environment,[14][15][16] with special emphasis on analyses that use GIS data.[23][24]

    High-level agent-based language

    [edit | edit source]

    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.[5]

    This high-level language was inspired by Smalltalk and Java, GAMA has been developed to be used by non-computer scientists.[5]

    User interface

    [edit | edit source]

    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.[5]

    Project examples

    [edit | edit source]

    The developers maintain a community-sourced list of scientific projects that use GAMA.[25]

    Some of the larger efforts include:

    • Hoan Kiem Air:[14] Agent based modeling and simulation of the urban management on traffic and air pollution through tangible interface.
    • Proxymix:[26] Visualization tool about the influence of spatial configuration on human collaboration.
    • CityScope Champs-Elysées:[15] An interactive platform to improve decision-making related to the revitalization of the Champs Élysées.
    • ESCAPE:[16] A Multi-modal Urban Traffic Agent-Based Framework to Study Individual Response to Catastrophic Events.
    • COMOKIT:[19][20] 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

    [edit | edit source]

    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,[27] and at the University of Salzburg.[28] It is also used and taught annually at the Multi-platform International Summer School on Agent-Based Modelling & Simulation.[29]
