Collective behaviour and swarm intelligence
How do groups of small brained (or no brained) organisms solve complex optimisation problems?
Some of the most powerful and flexible optimisation algorithms to be developed in recent years have been inspired by natural systems: these include genetic algorithms, artificial neural networks and ant colony optimisation algorithms. The natural world represents a gold mine of problem solving algorithms, yet this potential is largely untapped, primarily because biologists have yet to understand the behavioural mechanisms underlying problem solving in many systems. We aim to fill this knowledge gap by dissecting the behaviours that allow ant colonies, bee hives, and slime mould amoebas to collectively make ‘smart’ decisions.
At the moment, we have three funded projects investigating collective behaviour and swarm intelligence.
1. Bio-inspired solutions for protecting critical infrastructure systems (Funded by the Branco Weiss- Society in Science Fellowship)
2. Managing risk in supply chains using bio-inspired algorithms (Funded by the Australian Research Council)
3. Dynamic foraging in bees, ants and slime moulds (Funded by the Australian Research Council)
