Simulating Multi-Agent Turf Wars in r/place: Only 0.49% Overwrites
infoxiao · x · 2026-08-20
The author used the r/place mechanism as an environment to simulate multi-agent behavior. The experiment set up 3 agents (powered by Codex) competing to color a central region of the canvas in their assigned colors, allowing one pixel change and a message per step. Across 20 simulations of 24 steps each, results showed that with clear disclosure and a communication channel, agents from the same model family fought very little (only 0.49% overwrites). Agreements were reached quickly and states stabilized, demonstrating the effectiveness of communication in coordination.
