When less is more: Robot swarms adapt better to changes with constrained communication

MS Talamali, A Saha, JAR Marshall, A Reina - Science Robotics, 2021 - science.org
To effectively perform collective monitoring of dynamic environments, a robot swarm needs
to adapt to changes by processing the latest information and discarding outdated beliefs. We …

Magnitude-sensitivity: rethinking decision-making

A Pirrone, A Reina, T Stafford, JAR Marshall… - Trends in cognitive …, 2022 - cell.com
Magnitude-sensitivity refers to the result that performance in decision-making, across
domains and organisms, is affected by the total value of the possible alternatives. This …

Cross-inhibition leads to group consensus despite the presence of strongly opinionated minorities and asocial behaviour

A Reina, R Zakir, G De Masi, E Ferrante - Communications Physics, 2023 - nature.com

large population. Two factions of inflexible minorities, polarised into two competing opinions …

Analysis and control of agreement and disagreement opinion cascades

A Franci, A Bizyaeva, S Park, NE Leonard - Swarm Intelligence, 2021 - Springer
We introduce and analyze a continuous time and state-space model of opinion cascades on
networks of large numbers of agents that form opinions about two or more options. By …

Coherent collective behaviour emerging from decentralised balancing of social feedback and noise

I Rausch, A Reina, P Simoens, Y Khaluf - Swarm Intelligence, 2019 - Springer
Decentralised systems composed of a large number of locally interacting agents often rely
on coherent behaviour to execute coordinated tasks. Agents cooperate to reach a coherent …

Collective decision-making in living and artificial systems

A Reina, E Ferrante, G Valentini - Swarm Intelligence, 2021 - Springer
Collective decision-making is a fundamental cognitive process required for group
coordination. Typically, this process requires individuals in a group to either reach a …

Discrete collective estimation in swarm robotics with distributed Bayesian belief sharing

Q Shan, S Mostaghim - Swarm Intelligence, 2021 - Springer
