The center of the expansion is the center of the checker board. |
No it isn't. If a set of points placed at the intersections on a square grid around a central point expand uniquely from that central point
n distance per unit of time, the grid structure initially defined by those points will
not be maintained (get some graph paper and see). On the other hand, what I described is the case where the points expand apart and the grid structure
is maintained, and in that case there is no center of expansion; the expansion behavior favors no point.
