Why agent-based modeling? In the interview below Doyne Farmer discuses his work with Rob Axtell and John Geanakoplos, who aim to create an agent-based model of the U.S. economy that will people make better understand past, and future, financial c…

Continue reading »The concept of entropy has arisen periodically during the course of my PhD study, both as an analog to thermodynamics operationalised by Alan Wilson in his ‘family’ of spatial interaction models and to Shannon’s entropy as formalised spatially by several scholars including Mike Batty. Alan Wilson’s models of urban systems work because modelling an entropy […]

One of the things that I love about London is the easy access to relatively ‘wild’ (i.e. un-managed) areas from parts of the city that are wholly urban. We owe this, of course, to the existence of the green belt which, even as it allows me to scavenge for fresh, free food (see recipes below), …

Unfortunately, arithmetic means don’t work for angular data, this is because it cannot account for the circular nature of the distribution of angular measurements. For instance the angles 5 […]
