Sep 15, 2012 at 11:59 comment added Stephen Shea On the note: Doesn't blocking visited vertices for a fixed positive time in 1-d imply that the walker never visits the same vertex twice? The more general question seems to be related to the theory of reinforced random walks (or even once reinforced random walks). There may be methods in that literature that would be useful to you.
