Evolving Transport Networks — •Janosch Brandhorst and Pawel Romanczuk — Institute for Theoretical Biology, Department of Biology, Humboldt Universität zu Berlin, Germany

Ant colonies and slime moulds are known to effectively explore and exploit their environment by setting up a complex transport network. Interestingly, the scales of these networks are much larger than the area a single agent of these colonies can sense. Here, we present an agent-based model of a collective which adapts to explore and exploit arbitrary resource fields. Agents are stationary placed on an randomly generated resource field. In each iteration, an agent can harvest resources from the resource field and collect resources from its neighbours. The efficiency of these processes is dependent on the phenotype of each agent. The phenotype is allowed to evolve during the simulation. The performance of this collective is measured by the amount of resources which is delivered to the centre of the collective. This leads to the self-organized formation of a transport system which effectively assimilates randomly spatial distributed resources in its centre, even though the agents do not have any information about their neighbours, the location of resources nor the location of centre of the collective. Eventually, we are interested in the ability of such collective to adapt to spatio-temporally varying environments.
