WebFeb 23, 2024 · There are two principles to be followed in the whole expansion process: (1) When selecting vertices into the boundary set, try to minimize the increase of vertex replications. (2) During expansion, try to allocate additional edges which do not increase the replication vertices anymore. Webarea without the boundary Deﬁnition 4 Given a plane graph G(V,E), a faceof G is a maximal region of the plane if the vertices and the edges of G are removed. An unbounded (inﬁnite) face of G is called exterior, or outer face. The vertices and the edges of G that are incident with a face F form the boundaryof F. 3 jordan and associates washing machine repair

Webboundary edges. For each vertex on the boundary of the polygon, we have a ver-tex in this graph and if two vertices of the polygon see each other there is an edge between their corresponding vertices in the graph. Two vertices of a polygon see each other if and only if their connecting line segment completely lies inside the polygon, Weba connected graph has exactly two boundary vertices if and only if it is a path. In addition, they described all connected graphs with exactly three boundary vertices. Theorem 1 (Hasegawa and Saito [4]).
