A near-polygonal graph is a graph which has a set C of m-cycles for some positive integer m such that each 2-path of is contained in exactly one cycle in C. If m is the girth of then the graph is called polygonal. Given a polygonal graph of valency r and girth m, Archdeacon and Perkel proved the exi
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 Ε½ . 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
