This paper present a novel algorithm for monotone front propagation of anisotropic nature. In several examples the new algorithm is shown to be fast and able to solve a general class of front propagation problems. The algorithm is inspired by Huygens' principle in that the front is described using a list of nodes that are used as source points to evolve the front. Nodes affected by the source points are either directly used as source points or temporarily paused, depending on their solution value and the average solution value of all source points. This feature makes the algorithm semi-ordered. Still, nodes may be used as source points several times, making the algorithm iterative of nature. Together, these features create the Semi-Ordered Fast Iterative (SOFI) method.
