โœฆ Synopsis


This note combines the lazy randomized incremental construction scheme with the technique of "connectivity acceleration" to obtain an 0( n( log* n)*) time randomized algorithm to compute a single face in the overlay of two simple polygons in the plane. @

Given an n-vertex simple polygon P, the problem of computing the shortest weakly visible subedge of P is that of finding a shortest line segment s on the ลฝ . boundary of P such that P is weakly visible from s if s exists . In this paper, we present new geometric observations that are useful for solv
