Webb32find min-linkrectilinearpaths in rectilinear polygonal domains. 33Previous Work. Linear-time algorithms have been given for finding min-link 34paths in simple polygons [9,10,21–23]. The link distance map can also be built 35in linear time [21–23] for simple polygons, with the standard query performance. WebbSuch paths have already been studied, e.g. in [4, 9, 14, 15], where shortest rectilinear paths in the LI-metric are sought.
