Characterisation of reactive Nash equilibria in repeated additive games
Franziska Lesigang, Christian Hilbe, Nikoleta E. Glynatsi
In this paper, we study reactive strategies in repeated additive games between two players with finitely many actions. Reactive strategies condition only on the opponent's previous…
Reviving, reproducing, and revisiting Axelrod's second tournament
Vincent Knight, Owen Campbell, Marc Harper +2
Direct reciprocity, typically studied using the Iterated Prisoner's Dilemma (IPD), is central to understanding how cooperation evolves. In the 1980s, Robert Axelrod organized two i…
Exact conditions for evolutionary stability in indirect reciprocity under noise
Nikoleta E. Glynatsi, Christian Hilbe, Yohsuke Murase
Indirect reciprocity is a key mechanism for large-scale cooperation. This mechanism captures the insight that in part, people help others to build and maintain a good reputation. T…
The co-evolution of direct, indirect and generalized reciprocity
Saptarshi Pal, Christian Hilbe, Nikoleta E Glynatsi
People often engage in costly cooperation, especially in repeated interactions. When deciding whether to cooperate, individuals typically take into account how others have acted in…
Conditional cooperation with longer memory
Nikoleta E. Glynatsi, Martin A. Nowak, Christian Hilbe
Direct reciprocity is a wide-spread mechanism for evolution of cooperation. In repeated interactions, players can condition their behavior on previous outcomes. A well known approa…
Evolution of reciprocity with limited payoff memory
Nikoleta E. Glynatsi, Alex McAvoy, Christian Hilbe
Direct reciprocity is a mechanism for the evolution of cooperation in repeated social interactions. According to this literature, individuals naturally learn to adopt conditionally…
Properties of Winning Iterated Prisoner's Dilemma Strategies
Nikoleta E. Glynatsi, Vincent Knight, Marc Harper
Researchers have explored the performance of Iterated Prisoner's Dilemma strategies for decades, from the celebrated performance of Tit for Tat to the introduction of the zero-dete…
Using a theory of mind to find best responses to memory-one strategies
Nikoleta E. Glynatsi, Vincent A. Knight
Memory-one strategies are a set of Iterated Prisoner's Dilemma strategies that have been praised for their mathematical tractability and performance against single opponents. This…
A bibliometric study of research topics, collaboration and centrality in the Iterated Prisoner's Dilemma
Nikoleta E. Glynatsi, Vincent A. Knight
This manuscript explores the research topics and collaborative behaviour of authors in the field of the Prisoner's Dilemma using topic modeling and a graph theoretic analysis of th…
Recognising and evaluating the effectiveness of extortion in the Iterated Prisoner's Dilemma
Vincent A. Knight, Marc Harper, Nikoleta E. Glynatsi +1
Since the introduction of zero-determinant strategies, extortionate strategies have received considerable interest. While an interesting class of strategies, the definitions of ext…
An Evolutionary Game Theoretic Model of Rhino Horn Devaluation
Nikoleta E. Glynatsi, Vincent Knight, Tamsin E. Lee
Rhino populations are at a critical level due to the demand for rhino horn and the subsequent poaching. Wildlife managers attempt to secure rhinos with approaches to devalue the ho…
Evolution Reinforces Cooperation with the Emergence of Self-Recognition Mechanisms: an empirical study of the Moran process for the iterated Prisoner's dilemma
Vincent Knight, Marc Harper, Nikoleta E. Glynatsi +1
We present insights and empirical results from an extensive numerical study of the evolutionary dynamics of the iterated prisoner's dilemma. Fixation probabilities for Moran proces…
Reinforcement Learning Produces Dominant Strategies for the Iterated Prisoner's Dilemma
Marc Harper, Vincent Knight, Martin Jones +3
We present tournament results and several powerful strategies for the Iterated Prisoner's Dilemma created using reinforcement learning techniques (evolutionary and particle swarm a…
An open reproducible framework for the study of the iterated prisoner's dilemma
Vincent Knight, Owen Campbell, Marc Harper +19
The Axelrod library is an open source Python package that allows for reproducible game theoretic research into the Iterated Prisoner's Dilemma. This area of research began in the 1…
