Many processes in the social sciences, in economics and in biology can be modelled by so-called `agent-based systems'. In these systems many `agents' interact together and produce complex behaviour from relatively simple rules. A good example is that of a traffic jam, which arises from the interaction of individual vehicles. The `agents' in complex systems represent these interacting units, they may be vehicles in a model of a traffic jam, traders in the context of a financial market, cancer cells, or genes in a model of developmental biology. In my talk I will discuss how ideas and methods from physics can be used to understand such agent-based models. In particular I will discuss the effects of randomness and chaos in applications in game theory, evacuation, evolution and economics. The talk is interactive with plenty of opportunities for the audience to get involved. No mathematical background or in-depth knowledge of physics are required, an interest in the topic and a general enthusiasm about physics is all that is needed.
Talks start at 18.30 with tea and coffee available from 18.00. All are welcome and all our talks are free to attend.
