WebAbstract. The least-action principle from the Wentzell-Freidlin theory of large deviations is exploited as a numerical tool for finding the optimal dynamical paths in spatially extended systems driven by a small noise. The action is discretized and a preconditioned BFGS method is used to optimize the discrete action. WebThis paper is organized as follows. We brieﬂy review the minimum action method with optimal linear time scaling in Section 2. We then develop our adaptivity strategy in Section 3. Numerical results are given in Section 4 followed by a discussion section. 2 Minimum action method (MAM) 2.1 The large deviation principle (LDP)
