> On the other hand, all dense old-world cities (London, Paris, Rome, even Tokyo, say) are... "dendritic". Not in the sense of the Alexander essay. It explicitly contrasts the interwoven connections of traditional cities with the artificial tree-like structure of modern planned cities. "Tree", in the sense that Alexander uses it in that essay, is a math tree (e.g., a binary tree in CS), not an organic tree. I highly recommend reading the essay for those who haven't seen it.
