Study models classic games with time-varying rewards

A mathematical modeling study applies randomly fluctuating payoffs, rather than fixed rewards, to evolutionary versions of the prisoner's dilemma, the game of chicken, and rock-paper-scissors, finding that variation produces new stable and bistable population states not seen in the static versions of these games.
“Given that chicken was basically the Cold War strategy, I'm even more amazed we all survived to face our next existential challenge.”
Chris Lee, Ars TechnicaResearchers (unnamed in coverage) authors of the game-theory modeling study

“If we take the prisoner’s dilemma as the classic game theory tool, it yields a depressing conclusion: Cooperation is a losing strategy. Yet even under the conditions set by the prisoner’s dilemma, we observe cooperation.” @arstechnica.com

囚人のジレンマは、報酬が一定なら「みんなが裏切る」という一点に収束する。だが報酬が時間とともに変動するという現実的な条件を加えてモデル化したところ、変動が大きいほど裏切り者側の均衡点が不安定になり、最終的に協力者だけが生き残る結果になった。不確実性は敵ではないのかもしれない。 https://arstechnica.com/science/2026/09/random-rewards-enrich-classic-game-theory-contests/ #ゲーム理論

Game theory says selfishness always wins. Add a little real-world randomness to the rewards, and cooperation suddenly survives. Turns out a stable environment favors cheaters — a messy one rewards trust.
