We illustrate the Link Solver software for computing 1-link shortest paths in weighted regions. The Link Solver implements a prune-and-search method that can be used to approximate an optimal solution within a user specified precision. The theoretical foundation of the method is a result stating that an optimal solution goes through a vertex of the subdivision. This result provides a way to discretize the problem with respect to vertices of interest which in turn leads to efficient algorithms.
