WebMinimum action method (MAM) plays an important role in seeking the most 6 probable transition pathway induced by small noise. There exist two formulations of minimum ac-7 tion method: one is the geometric formulation based on the Maupertuis principle; and the other one 8 is the temporal formulation. WebThe minimum action method (MAM)is to calculate the most probable tran-sition path in randomly perturbed stochastic dynamics, based on the idea of action minimization in the path space. The accuracy of the numerical path between differ-ent metastable states usually suffers from the “clustering problem” near ﬁxed points.
