"Webb27 dec. 2016 · In the traditional shortest path problem inside a simple polygon, the input consists of P and a pair of points s,t \in P; the objective is to connect s and t by a path in P of minimum length. Here a path is a sequence of line segments, called the edges of the path; the path changes the direction (or turns) only at the vertices of P. " - Smallest paths in simple rectilinear polygons
