Measuring unequal distribution of pandemic severity across census years, variants of concern and interventions

no code implementations26 Jun 2023 Quang Dang Nguyen, Sheryl L. Chang, Christina M. Jamerlan, Mikhail Prokopenko

However, a systematic analysis and modelling of the combined effects of different viral lineages and complex intervention policies remains a challenge.

Persistence of the Omicron variant of SARS-CoV-2 in Australia: The impact of fluctuating social distancing

no code implementations20 Nov 2022 Sheryl L. Chang, Quang Dang Nguyen, Alexandra Martiniuk, Vitali Sintchenko, Tania C. Sorrell, Mikhail Prokopenko

Our study delineated distinct phases of the Omicron-associated pandemic stage, and retrospectively quantified the adoption of social distancing measures, fluctuating over different time periods in response to the observable incidence dynamics.

The effects of local homogeneity assumptions in metapopulation models of infectious disease

no code implementations2 Dec 2021 Cameron Zachreson, Sheryl Chang, Nathan Harding, Mikhail Prokopenko

While compartmental models can be structured to separate distinct sectors of a population, they are conceptually distinct from individual-based models in which population structure emerges from micro-scale interactions.

Simulating transmission scenarios of the Delta variant of SARS-CoV-2 in Australia

no code implementations14 Jul 2021 Sheryl L. Chang, Oliver M. Cliff, Cameron Zachreson, Mikhail Prokopenko

An outbreak of the Delta (B. 1. 617. 2) variant of SARS-CoV-2 that began around mid-June 2021 in Sydney, Australia, quickly developed into a nation-wide epidemic.

Bounded rationality for relaxing best response and mutual consistency: The Quantal Hierarchy model of decision-making

1 code implementation30 Jun 2021 Benjamin Patrick Evans, Mikhail Prokopenko

We demonstrate the effectiveness of the Quantal Hierarchy model in several canonical economic games, {both simultaneous and sequential}, using out-of-sample modelling.

How will mass-vaccination change COVID-19 lockdown requirements in Australia?

no code implementations12 Mar 2021 Cameron Zachreson, Sheryl L. Chang, Oliver M. Cliff, Mikhail Prokopenko

For realistic scenarios in which herd immunity is not achieved, we simulate the effects of mass-vaccination on epidemic growth rate, and investigate the requirements of lockdown measures applied to curb subsequent outbreaks.

A maximum entropy model of bounded rational decision-making with prior beliefs and market feedback

no code implementations18 Feb 2021 Benjamin Patrick Evans, Mikhail Prokopenko

Specifically, it allowed for the separation of past beliefs and utility maximisation behaviour of the agent as well as the analysis into the evolution of agent beliefs.

Beyond COVID-19: Network science and sustainable exit strategies

no code implementations27 Sep 2020 James Bell, Ginestra Bianconi, David Butler, Jon Crowcroft, Paul C. W Davies, Chris Hicks, Hyunju Kim, Istvan Z. Kiss, Francesco Di Lauro, Carsten Maple, Ayan Paul, Mikhail Prokopenko, Philip Tee, Sara I. Walker

On May $28^{th}$ and $29^{th}$, a two day workshop was held virtually, facilitated by the Beyond Center at ASU and Moogsoft Inc.

An Ansatz for computational undecidability in RNA automata

no code implementations12 Aug 2020 Adam J. Svahn, Mikhail Prokopenko

Limited to these operations, we construct RNA automata of increasing complexity; from the Finite Automaton (RNA-FA) to the Turing Machine equivalent 2-stack PDA (RNA-2PDA) and the universal RNA-UPDA.

Explaining herding and volatility in the cyclical price dynamics of urban housing markets using a large scale agent-based model

no code implementations16 Apr 2020 Kirill S. Glavatskiy, Mikhail Prokopenko, Adrian Carro, Paul Ormerod, Michael Harre

The agents' behavior is compatible with economic rationality, with the trend-following behavior found to be essential in replicating market dynamics.

Modelling transmission and control of the COVID-19 pandemic in Australia

no code implementations23 Mar 2020 Sheryl L. Chang, Nathan Harding, Cameron Zachreson, Oliver M. Cliff, Mikhail Prokopenko

We then apply the model to compare several intervention strategies, including restrictions on international air travel, case isolation, social distancing with varying levels of compliance, and school closures.

Fractals2019: Combinatorial Optimisation with Dynamic Constraint Annealing

no code implementations4 Sep 2019 Mikhail Prokopenko, Peter Wang

Fractals2019 started as a new experimental entry in the RoboCup Soccer 2D Simulation League, based on Gliders2d code base, and advanced to become a RoboCup-2019 champion.

Inferring Coupling of Distributed Dynamical Systems via Transfer Entropy

no code implementations2 Nov 2016 Oliver M. Cliff, Mikhail Prokopenko, Robert Fitch

In this work, we are interested in structure learning for a set of spatially distributed dynamical systems, where individual subsystems are coupled via latent variables and observed through a filter.

An Information Criterion for Inferring Coupling in Distributed Dynamical Systems

no code implementations23 May 2016 Oliver M. Cliff, Mikhail Prokopenko, Robert Fitch

The behaviour of many real-world phenomena can be modelled by nonlinear dynamical systems whereby a latent system state is observed through a filter.

Information Transfer in Swarms with Leaders

no code implementations30 Jun 2014 Yu Sun, Louis F. Rossi, Chien-Chung Shen, Jennifer Miller, X. Rosalind Wang, Joseph T. Lizier, Mikhail Prokopenko, Upul Senanayake

Depending upon the leadership model, leaders can use their external information either all the time or in response to local conditions [Couzin et al. 2005; Sun et al. 2013].

Simulation leagues: Analysis of competition formats

no code implementations17 Mar 2014 David Budden, Peter Wang, Oliver Obst, Mikhail Prokopenko

A proposed new competition format is found to reduce variation from the resultant statistically significant team performance rankings by 75% and 67%, when compared to the actual competition results from RoboCup 2012 and 2013 respectively.
