If no neighboring patch
has a larger value than the patch
where the
turtle
is currently located on, the turtle
stays on this patch
. It still
moves to the patch
center if it was not already on it.
If there are multiple neighboring `patches` with the same highest value, the `turtle` chooses one `patch` randomly. If a `turtle` is located on a `patch` on the edge of the `world` and `torus = FALSE`, it has fewer neighboring `patches` as options to move than `nNeighbors`; if `torus = TRUE`, the `turtle` can move on the other side of the `world` to move uphill and its choice of neighboring `patches` is always equals to `nNeighbors`.
