I'm searching for the minimum path between the minima of a potential surface that is already known on a grid.
(source: http://www.math.nus.edu.sg/~matrw/string/)
Any point on the path is at an potential minimum in all directions perpendicular to the path.
Is there any SciPy method or any other python package to compute this path? I'm not looking for a method that can search on an unknown surface.
edit: I'm searching the path with the lowest potential barrier.
