Imitation dynamics in population games on community networks

G Como, F Fagnani, L Zino - IEEE Transactions on Control of …, 2020 - ieeexplore.ieee.org
In this article, we study the asymptotic behavior of deterministic, continuous-time imitation
dynamics for population games over networks. The basic assumption of this learning …

Constrained evolutionary games by using a mixture of imitation dynamics

J Barreiro-Gomez, H Tembine - Automatica, 2018 - Elsevier
Game dynamics have been widely used as learning and computational tool to find
evolutionarily stable strategies. Nevertheless, most of the existing evolutionary game …

Heterogeneous mixed populations of best-responders and imitators: Equilibrium convergence and stability

H Le, P Ramazi - IEEE Transactions on Automatic Control, 2020 - ieeexplore.ieee.org
In anticoordination social contexts such as stock selection, resource allocation, and crowd
dispersion, an individual earns more if the opponents adopt her opposite strategy. Based on …

[HTML][HTML] The lower convergence tendency of imitators compared to best responders

P Ramazi, J Riehl, M Cao - Automatica, 2022 - Elsevier
Imitation is widely observed in nature and often used to model populations of decision-
making agents, but it is not yet known under what conditions a network of imitators will reach …

Rationality, imitation, and rational imitation in spatial public goods games

A Govaert, P Ramazi, M Cao - IEEE Transactions on Control of …, 2021 - ieeexplore.ieee.org
In both economic and evolutionary theories of games, two general classes of evolution can
be identified: 1) dynamics based on myopic optimization and 2) dynamics based on …

Relative best response dynamics in finite and convex network games

A Govaert, C Cenedese… - 2019 IEEE 58th …, 2019 - ieeexplore.ieee.org
Motivated by theoretical and experimental economics, we propose novel evolutionary
dynamics for games on networks, called the h-Relative Best Response (h-RBR) dynamics …

Asynchronous decision-making dynamics under imitation update rule in heterogeneous populations

Y Fu, P Ramazi - 2019 IEEE 58th Conference on Decision and …, 2019 - ieeexplore.ieee.org
Decision-making individuals are often likely to imitate their highest-earning fellows rather
than optimizing their own utilities, due to bounded rationality and incomplete information on …

Heterogeneous mixed populations of coordinating, anticoordinating, and imitating individuals

H Le, M Rajaee, P Ramazi - arxiv preprint arxiv:2202.04782, 2022 - arxiv.org
Decision-making individuals are typically either an imitator, who mimics the action of the
most successful individual (s), a conformist (or coordinating individual), who chooses an …

Myxobolus cerebralis establishment and spread: a graphical synthesis

P Ramazi, SM Fischer, J Alexander… - Canadian Journal of …, 2022 - cdnsciencepub.com
Myxobolus cerebralis is the parasite causing whirling disease, which has dramatic
ecological impacts due to its potential to cause high mortality in salmonids. The large-scale …

Evolutionary matrix-game dynamics under imitation in heterogeneous populations

Y Fu, P Ramazi - Automatica, 2024 - Elsevier
Perpetual fluctuations between decisions are reported as the dominant asymptotic outcome
of imitative behaviours, yet little attempt has been made to characterize them, particularly in …
