Think twice about eliminating those pesky ants at your next family picnic. Their behavior may hold the key to reinventing how engineering materials, traffic control and multi-agent robots are made and utilized, thanks to research conducted by recent graduate Matthew Loges '25 and Assistant Professor Tomer Weiss from NJIT's Ying Wu College of Computing.
The two earned a best presentation award for their research paper titled "Simulating Ant Swarm Aggregations Dynamics" at the ACM SIGGRAPH Symposium for Computer Animation (SCA), and a qualifying poster nomination for the undergraduate research competition at the 2025 ACM SIGGRAPH conference.
SIGGRAPH, Special Interest Group on Computer Graphics and Interactive Techniques, is considered among the most prestigious in the areas of computer graphics and AI.
Their study began in with the observation that ant swarms behave in a manner similar to both fluid and elastic materials and the duo got to work in the summer of 2024. Loges started being interested in research after he took an elective class with Weiss, IT 360 Computer Graphics for Visual Effects, at the Department of Informatics. This was his first project and research paper. According to Weiss, there is much motivation in replicating ant swarm behavior. Ants behave as a sort of active matter that morphs and adjust in shape as needed – if you try to cut a blob of ants, it will just reform to its original shape. This can lead to new discoveries in engineering materials such as smart, self-healing concrete, or innovations in navigation of multi-agent robots and traffic control.
Weiss's broader research spans computer graphics, physics-based simulations and AI-driven modeling of natural phenomena. He notes that understanding how biological systems like ant swarms exhibit both fluid and elastic properties offers a foundation for creating new algorithms that bridge biology and computer science. His group's aim is not only to simulate realistic behaviors but also to translate those findings into practical innovations in material science, robotics and large-scale systems.
The research team then went about successfully designing a computational simulation algorithm that could incorporate both the fluid and elastic real-world behavior of ants observed in lab experiments.
