Alasdair is right, of course, although, to my knowledge, there aren't any
publications in the animat series of conferences which touch on space
syntax. For those who don't know about this, the animat community has been
working on simulation of adaptive behaviour since the early 90s (led, here
in the UK, by Dave Cliff and Phil Husbands).
