Momentum Accelerates Evolutionary Dynamics

no code implementations5 Jul 2020 Marc Harper, Joshua Safyan

We combine momentum from machine learning with evolutionary dynamics, where momentum can be viewed as a simple mechanism of intergenerational memory.

Reinforcement Learning Produces Dominant Strategies for the Iterated Prisoner's Dilemma

1 code implementation19 Jul 2017 Marc Harper, Vincent Knight, Martin Jones, Georgios Koutsovoulos, Nikoleta E. Glynatsi, Owen Campbell

We present tournament results and several powerful strategies for the Iterated Prisoner's Dilemma created using reinforcement learning techniques (evolutionary and particle swarm algorithms).

An open reproducible framework for the study of the iterated prisoner's dilemma

no code implementations4 Apr 2016 Vincent Knight, Owen Campbell, Marc Harper, Karol Langner, James Campbell, Thomas Campbell, Alex Carney, Martin Chorley, Cameron Davidson-Pilon, Kristian Glass, Nikoleta Glynatsi, Tomáš Ehrlich, Martin Jones, Georgios Koutsovoulos, Holly Tibble, Müller Jochen, Geraint Palmer, Piotr Petunov, Paul Slavin, Timothy Standen, Luis Visintini, Karl Molden

With a growing collection of 139 strategies, the library is a also a platform for an original tournament that, in itself, is of interest to the game theoretic community.

Inferring Fitness in Finite Populations with Moran-like dynamics

1 code implementation19 Mar 2013 Marc Harper

Biological fitness is not an observable quantity and must be inferred from population dynamics.

Stability of Evolutionary Dynamics on Time Scales

1 code implementation19 Oct 2012 Marc Harper, Dashiell E. A. Fryer

We combine incentive, adaptive, and time-scale dynamics to study multipopulation dynamics on the simplex equipped with a large class of Riemmanian metrics, simultaneously generalizing and extending many dynamics commonly studied in dynamic game theory and evolutionary dynamics.
