[starlogo-users] city modeling with starlogo and cellular automata

[joe lambke]

interesting too!

years ago, i presented a paper at a conference in 1998 with a Starlogo 
city model.

Sixth International Artificial Life Conference
http://www.animatearchitecture.com/04_04.html
Evolution of Places (84 K)
MIT Press, 1998


as an architect i recognize the impact of spatial models, however the 
starlogo model I created is based on human interactions which drive the 
development of the landscape.

I'd like to do more research in this area, but haven't found the right 
opportunity...
If anyone knows where this type of inquiry would be valued, I'd be 
interested to hear.

thanks

joe
