Combination with anti-tit-for-tat remedies problems of tit-for-tat.
One of the most important questions in game theory concerns how mutual cooperation can be achieved and maintained in a social dilemma. In Axelrod's tournaments of the iterated prisoner's dilemma, Tit-for-Tat (TFT) demonstrated the role of reciprocity in the emergence of cooperation. However, the stability of TFT does not hold in the presence of implementation error, and a TFT population is pron...
متن کاملTit-for-Tat Distributed Resource Allocation
Distributed computing infrastructures have risen in popularity over the past decade, however resource allocation on these—largely federated—systems remains a practically unsolved problem. Previous attempts have either relied upon central management of resources, which is infeasible in a federated model, and market-based economies which we classify into systems using global, transferrable curren...
متن کاملWhen is tit-for-tat unbeatable?
We characterize the class of symmetric two-player games in which tit-for-tat cannot be beaten even by very sophisticated opponents in a repeated game. It turns out to be the class of exact potential games. More generally, there is a class of simple imitation rules that includes tit-for-tat but also imitate-the-best and imitate-if-better. Every decision rule in this class is essentially unbeatab...
متن کاملEnhancing tit-for-tat for incentive in BitTorrent networks
BitTorrent achives great success in its high performance for file distribution. It is commonly believed that this owes to Tit-for-Tat strategy adopted in choking algorithm for incentive in BitTorrent protocol. But there are still many issues in incentive mechanism in BitTorrent. In this paper, we study Tit-for-Tat strategy by constructing a game model in P2P environments and deducing the constr...
متن کاملTit-for-Tat: Type VI Secretion System Counterattack during Bacterial Cell-Cell Interactions
The bacterial type VI secretion system (T6SS) is a dynamic organelle that bacteria use to target prey cells for inhibition via translocation of effector proteins. Time-lapse fluorescence microscopy has documented striking dynamics of opposed T6SS organelles in adjacent sister cells of Pseudomonas aeruginosa. Such cell-cell interactions have been termed "T6SS dueling" and likely reflect a biolog...
