Transformer Guided Coevolution: Improved Team Selection in Multiagent Adversarial Team Games

2024-10-17 · Pranav Rajbhandari, Prithviraj Dasgupta, Donald Sofge

We consider the problem of team selection within multiagent adversarial team games. We propose BERTeam, a novel algorithm that uses a transformer-based deep neural network with Masked Language Model training to select the best team of players from a trained population. We integrate this with coevolutionary deep reinforcement learning, which trains a diverse set of individual players to choose from. We test our algorithm in the multiagent adversarial game Marine Capture-The-Flag, and find that BERTeam learns non-trivial team compositions that perform well against unseen opponents. For this game, we find that BERTeam outperforms MCAA, an algorithm that similarly optimizes team selection.

Evolutionary and Coevolutionary Multi-Agent Design Choices and Dynamics

2025-07-07 · Erik Hemberg, Eric Liu, Lucille Fuller, Stephen Moskal 외

We investigate two representation alternatives for the controllers of teams of cyber agents. We combine these controller representations with different evolutionary algorithms, one of which introduces a novel LLM-support…

Coevolutionary patterns caused by prey selection

2020-05-19

Many theoretical models have been formulated to better understand the coevolutionary patterns that emerge from antagonistic interactions. These models usually assume that the attacks by the exploiters are random, so the …

Analyzing the Components of Distributed Coevolutionary GAN Training

2020-08-03 · Jamal Toutouh, Erik Hemberg, Una-May O'Reilly

Distributed coevolutionary Generative Adversarial Network (GAN) training has empirically shown success in overcoming GAN training pathologies. This is mainly due to diversity maintenance in the populations of generators …
