Game-environment feedback dynamics in growing population: Effect of finite carrying capacity

J Das Bairagya, SS Mondal, D Chowdhury… - Physical Review E, 2021 - APS
The tragedy of the commons (TOC) is an unfortunate situation where a shared resource is
exhausted due to uncontrolled exploitation by the selfish individuals of a population …

Evolutionary dynamics of the delayed replicator-mutator equation: Limit cycle and cooperation

S Mittal, A Mukhopadhyay, S Chakraborty - Physical Review E, 2020 - APS
Game theory deals with strategic interactions among players and evolutionary game
dynamics tracks the fate of the players' populations under selection. In this paper, we …

Deciphering chaos in evolutionary games

A Mukhopadhyay, S Chakraborty - Chaos: An Interdisciplinary Journal …, 2020 - pubs.aip.org
A discrete-time replicator map is a prototype of evolutionary selection game dynamical

Discretizing and validating Keyfitz'entropy for any demographic classification

S Giaimo - Methods in Ecology and Evolution, 2024 - Wiley Online Library
Keyfitz's entropy originally is a shape measure of senescence for continuous‐time models.
But a later formula of Keyfitz's entropy for discrete time also exists. de Vries et al.(2023) …

Chaos and coexisting attractors in replicator-mutator maps

A Mukhopadhyay, S Chakraborty… - Journal of Physics …, 2021 - iopscience.iop.org
Mutation is an unavoidable and indispensable phenomenon in both biological and social
systems undergoing evolution through replication-selection processes. Here we show that …

The impact of exploration on convergence and performance of multi-agent Q-learning dynamics

A Hussain, F Belardinelli… - … Conference on Machine …, 2023 - proceedings.mlr.press
Understanding the impact of exploration on the behaviour of multi-agent learning has, so far,
benefited from the restriction to potential, or network zero-sum games in which convergence …

Asymmetric Replicator Dynamics on Polish Spaces: Invariance, Stability, and Convergence

KD Lewis, AJ Shaiju - Dynamic Games and Applications, 2024 - Springer
We study a class of asymmetric games with compact Polish strategy sets and provide
sufficient conditions for the stability and convergence of profiles under the infinite …

Periodic orbit can be evolutionarily stable: Case study of discrete replicator dynamics

A Mukhopadhyay, S Chakraborty - Journal of theoretical biology, 2020 - Elsevier
In evolutionary game theory, it is customary to be partial to the dynamical models
possessing fixed points so that they may be understood as the attainment of evolutionary …

Replicator equations induced by microscopic processes in nonoverlapping population playing bimatrix games

A Mukhopadhyay, S Chakraborty - Chaos: An Interdisciplinary Journal …, 2021 - pubs.aip.org
This paper is concerned with exploring the microscopic basis for the discrete versions of the
standard replicator equation and the adjusted replicator equation. To this end, we introduce …

Reward versus punishment: averting the tragedy of the commons in eco-evolutionary dynamics

SS Mondal, M Pathak… - Journal of Physics …, 2022 - iopscience.iop.org
