T3 - ELSE Working Papers CY - London, UK N2 - We introduce a simple adaptive rule where agents choose a cooperative effort on a grid. Agents can adjust this effort step by step and Gains and Losses Adjust Directions. We show that this process con- verges to the cooperative outcome in a two-person Prisoners' Dilemma game, and we provide simulations showing that the results also holds with a larger number of agents.
