WebNov 21, 2015 · The fast marching method is as follows. Suppose at some time the Eikonal solution is known at a set of Accepted points. For every not-yet accepted grid point with an Accepted neighbor, we compute a trial solution to the above quadratic Eq. 2, using the given values for u at accepted points and values of \infty at all other points. The fast marching method takes advantage of this optimal control interpretation of the problem in order to build a solution outwards starting from the "known information", i.e. the boundary values. The algorithm is similar to Dijkstra's algorithm and uses the fact that information only flows outward … See more The fast marching method is a numerical method created by James Sethian for solving boundary value problems of the Eikonal equation: $${\displaystyle \nabla u(x) =1/f(x){\text{ for }}x\in \Omega }$$ See more • Dijkstra-like Methods for the Eikonal Equation J.N.
