Figure 1:

The system used for the numerical experiments in Section 4. (left) Müller-Brown potential [58]. Sets $A$ and $B$ are marked by the orange and red ellipses, respectively, and contours are spaced at intervals of 1 in the units of (14). (right) Reference committor for the Müller-Brown dynamics mapped to the Swiss roll, and below on the two-dimensional surface. We compute the reference from a finite difference scheme [38] in two dimensions and then map it to the Swiss roll using (17).
