Fast Marching Methods for Indefinite and Anisotropic Metrics [PDF]
, 2011 In this thesis two different variants of the Fast-Marching-Method (FMM) are discussed. The first variant is an extension of the Generalized-Fast-Marching-Method to unstructured triangulations. We preserve the analytic properties as far as possible. Likewise to the GFMM there also is a modification which preserves the monotonicity.

A Multilevel Fast Marching Method for the Minimum Time Problem
SIAM Journal on Control and OptimizationWe introduce a new numerical method to approximate the solutions of a class of stationary Hamilton-Jacobi (HJ) partial differential equations arising from minimum time optimal control problems. We rely on nested grid approximations, and look for the optimal trajectories by using the coarse grid approximations to reduce the search space in fine grids ...
