Lower Bound of Face Guards of Polyhedral Terrains

Name: Work Video:
Duration: 3 min 30 s
Description: We study the problem of determining the minimum number of face guards which cover the surface of a polyhedral terrain. We show that ⌊(2n-5)/7⌋ face guards are sometimes necessary to guard the surface of an n-vertex triangulated polyhedral terrain.
