Hi Jean-Michel,

You can't change the tile index to (1,1), it needs to stay at (2,2).
Reason is that the cost function is meridional heat transport
across 26N in Atlantic, and over 10 timesteps it's not
sensitive to changes in the South Pacific.
If you move the test locations too far away from the cost location,
you'll be testing numerical noise.
