Biologists rely extensively on the iterated Prisoner's Dilemma game to model reciprocal altruism. After examining the informal conditions necessary for reciprocal altruism, I argue that formal games besides the standard iterated Prisoner's Dilemma meet these conditions. One alternate representation, the modified Prisoner's Dilemma game, removes a standard but unnecessary condition; the other game is what I call a Cook's Dilemma. We should explore these new models of reciprocal altruism because… 
This paper is a contribution to solving the problem of whether reciprocal altruism can emerge and maintain itself in a population of selfish individuals. We use an evolutionary game theoretic

A study of Institutional Change in Common-pool Resources Governance Model: Based on Reciprocal Altruistic Game Theory
Abstract: Reciprocal altruism offers the possibility of dynamic cooperation in the game of the prisoner's dilemma. Through the reciprocal altruism game model, the cooperative behavior of actors in

Agents' Cooperation Based on Long-Term Reciprocal Altruism
In FRAM, agent has a controllable rate of tolerance and is willing to grant favors for long-term return, and can determine whether to grant a favor to another based on their past interactions, so granting unmatched favors by accident will not break the relationship between two agents immediately.
Emotional Reactions to Conditional Rules of Reciprocal Altruism
A seminal article on the evolution of social behavior (Trivers, 1971) outlined a number of emotional responses that were predicted to result from various reciprocal altruism (RA) situations. These
Dynamic Spectrum Sharing in Femtocells: A Comparison of Selfish versus Altruistic Strategies
A game theoretic model for a dynamic spectrum sharing framework recently proposed for femtocells is presented and results show that strict adherence to the game-theoretic selfish behavior performs poorly compared to the non-adherent rules which balance altruism and rational egoism.
Gifting in Multi-Agent Reinforcement Learning
This work introduces peer rewarding, in which agents can deliberately influence each others’ reward function, and empirically study gifting, a peer rewarding mechanism which allows agents to reward other agents as part of their action space.

Is the repeated prisoner's dilemma a good model of reciprocal altruism?
The Alternating Prisoner's Dilemma
Abstract Reciprocal altruism can often be modelled by a variant of the iterated Prisoner's Dilemma where players alternate in the roles of donor and recipient, rather than acting simultaneously. We
A strategy of win-stay, lose-shift that outperforms tit-for-tat in the Prisoner's Dilemma game
Extended evolutionary simulations of heterogeneous ensembles of probabilistic strategies including mutation and selection are presented and the unexpected success of another protagonist: Pavlov is reported, suggesting that cooperative behaviour in natural situations may often be based on win-stay, lose-shift.
The evolution of cooperation.
A model is developed based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game to show how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established.

A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate against the cheater (non-reciprocator) in the
Reciprocal food sharing in the vampire bat
It is shown that food sharing by regurgitation of blood among wild vampire bats (Desmodus rotundus) depends equally and independently on degree of relatedness and an index of opportunity for recipro cation.

Reciprocal altruism in Papio anubis
It is reported here that altruistic behaviour involving the formation of coalitions among male olive baboons (Papio anubis) fulfils the criteria for reciprocal altruism.
Evolution and the Theory of Games
It is beginning to become clear that a range of problems in evolution theory can most appropriately be attacked by a modification of the theory of games, a branch of mathematics first formulated by Von Neumann and Morgenstern in 1944 for the analysis of human conflicts.
