Ultimatum Game (2D): Fairness & Evolving Offers

2D canvas companion to the 3D Ultimatum Game: a population of agents plays the ultimatum game generation after generation, evolving offer and minimum-acceptable-offer strategies that converge near a fair 40-50% split rather than the game-theoretic 0% prediction.

A 2D canvas companion to the 3D Ultimatum Game, rendering the identical evolutionary model. A population of agents repeatedly plays the ultimatum game; each generation the offer and minimum-acceptable-offer strategies of poorly-performing agents drift toward those of better-performing ones, subject to random mutation. Watch the offer histogram and the agent grid converge toward fairness over successive generations.

2D companion to the Ultimatum Game: the same repeated-play, imitation-based evolutionary dynamic, rendered with flat Canvas 2D discs and a live offer histogram instead of WebGL/Three.js.
