Talk:Brownian tree

Note that "collide" is not defined. In one implementation "collide" means that the particle lands on a fixed particle (and then its previous position is used). In another implementation (mine), "collide" means that the particle reaches a position adjacent to a fixed particle. I do not know if this ambiguity matters, but I thought I would mention it. --Rdm 11:54, 14 July 2010 (UTC)

It's interesting, but I don't think it matters; there are enough differences between languages that a retrace step in the algorithm doesn't seem important. --Michael Mol 16:38, 14 July 2010 (UTC)
