Wednesday morning was the main reason I was here - the symposium on "Agent-Based Modelling of Land-use Effects", organised by Gary Polhill. It started with Gary giving us a quick run overview of ABM "so the rest of the presenters don't have to". A couple of references of interest were:
The second day at US-IALE was mostly taken up with the Coupled Human and Natural Systems (CHANS) discussion. This is a funding stream within the NSF, aimed towards funding interdisciplinary work in the area of coupled human and natural systems (although there is some dissent about the "coupled" part of it, as people feel that we should see it more as one system!).
This week I'm attending the US-IALE conference in Snowbird, Utah, with the tagline "Coupling Humans and Complex Ecological Landscapes". We kicked off with a keynot from Thomas Baerwald, from the NSF, about "Facilitating the Conduct of Naturally Humane and Humanely Natural Research".
Started off in the Social Networks and Multi-Agent Systems room again, a talk by Davide Donetto, about "The emergence of shared social representations in complex networks". He talked about the difference between "reified" roles, which are selected by rules according to competences, and "consensual" roles, which are freely chosen by the agents. His model involved a social network of agents, constructed with a small world distribution, so that when a new node is added, the probability of it linking to an existing node is proportional to the share of the links that node has:
I'm attending AISB09 in Edinburgh, talking about "Adaptive and Emergent Behaviour and Complex Systems"
I started in the Social Networks and Multi Agent Systems symposium, with "Leon van der Torre and Serena Villata. Four Ways to Change Coalitions: Agents, Dependencies, Norms and Internal Dynamics". They're looking at the way coalitions change, in groups of agents represented using dependence networks. They give four types of change: agents, their dependencies, the addition of norms and internal coalition processes, and then talk about metrics for stability.
