- How to build the network of contacts : selecting the cooperative partnersPublication . Mariano, Pedro; Correia, Luís; Grilo, Carlos Fernando AlmeidaWe address the problem of finding the correct agents to interact with from a general standpoint. We take the payout obtained by agents in any game with dilemma as an input to our model. Its output is a probability distribution used in the partner selection that increasingly favours cooperative agents. Our approach contrasts with others designed for specific games without concerns of generality. We show both theoretically and experimentally that the major factor affecting cooperators selecting only themselves is the agents' strategies. This result does not depend on game nature or the initial probability distribution.
- Selection of cooperative partners in n-player gamesPublication . Mariano, Pedro; Correia, Luís; Grilo, Carlos Fernando AlmeidaWe address the problem of finding the appropriate agents to interact with in n-player games. In our model an agent only requires knowledge about the payoff and identification of its partners. This information is used to update a probability distribution over candidate partners. As such, our model is applicable in any situation, be it a cooperative dilemma or a game where a Nash Equilibrium is equal to a Pareto Optimal profile.
