Let G = (V, E) be any undirected graph on V vertices and E edges. A path P between any two vertices u, v ∈ V is said to be t-approximate shortest path if its length is at most t ...

When studying a 3D polyhedron, it is often easier to cut it open and
atten in on the plane. There are several ways to perform this unfolding. Standard unfoldings which have been u...
