The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
We have just wrapped up project that created a simple agent-based simulation of urban life as part of DARPA’s Ground Truth Program. To this end we have just published a new paper entitled “Urban life: a model of people and places” published in C…
