How GAMA Works
GAMA Platform enables agent-based modeling, where agents interact within a simulated environment using GAma Modeling Language (GAML). It supports GIS data integration, allowing realistic spatial simulations for urban planning, environmental studies, and disaster management.
Users can run real-time simulations with 2D/3D visualizations, modify parameters dynamically, and leverage AI and machine learning for adaptive agent behaviors. It also supports multi-core processing and GPU acceleration for handling large-scale models efficiently.
Simulation results can be exported in various formats, such as CSV, JSON, and XML, for further statistical analysis or reporting. GAMA integrates with Python, R, MATLAB, and databases, making it a versatile tool for researchers and professionals working on real-world simulations.
