Apr 17, 2012 at 17:20 comment added Gerhard Paseman You might be able to capitalize on the return time for an infinite grid. If it is O(n^2), then a return to the origin from a given direction is also O(n^2), and now you can traverse the grid in V^2*O(n^2) steps. Gerhard "Ask Me About System Design" Paseman, 2012.04.17
