The fast multipole method's algorithm is dependent upon the following steps: 1- At the finest level, start calculating multipole expansions in each and every partition. The fast marching method is a numerical method created by James Sethian for solving boundary value problems of the Eikonal equation: Typically, such a problem describes the evolution of a closed surface as a function of time with speed in the normal direction at a point on the propagating surface. The speed function is specified, and the time at which the contour crosses a point is obtained by solving the equation. …
