Haven't you wrote a gradient pathfinding algorithm yourself in pearl a
few month ago?
We don't calculate paths.  We calculate landscapes where each square
knows which of
its neighboring squares is closer to a kind of a resource.  To know on
which square
the "target resource" is, we would have to trace the whole path - for
every glob.

To say we know the path because we know the gradient landscape is somewhat like
saying we know the path because we know the map and the glob position.
