ART GALLERY THEOREMS AND ALGORITHMS - Clark Science Center The first chapter covers the original art gallery theorem (|/*/3j guards are necessary and sufficient), and basic polygon partitioning algorithms. I have found this material to form a suitable introduction to computational geometry.

The Art Gallery Problem - IIT The original art gallery problem (V. Klee, 1973) asked for the minimum number of guards sufficient to see every point of the interior of an n-vertex simple polygon. A simple polygon is a simply-connected closed region whose boundary consists of a finite set of line segments.

The Art Gallery Theorem Finding the minimal number of cameras is NP-hard. Exercise 1: Consider a simple (no holes) polygon P with n vertices, where all edges are either vertical or horizontal. The simplest example is a rectangle and 1 camera sufices. Draw examples to justify that ⌊n/4⌋ cameras sufice.

The Art Gallery Problem - Antonella PERUCCA How many surveillance cameras would you install, and where would you place them? Consider the Art Gallery Problem for a simple polygon (planar, closed and not self-intersecting) with n edges. Find examples for which one needs as many surveillance cameras as the quotient of n after division by 3.

The Art Gallery Problem: An Overview and Extension to ... The art gallery problem is formulated in geometry as the minimum number of guards that need to be placed in an n-vertex simple polygon such that all points of the interior are visible.

ORTHOGONAL POLYGONS - Clark Science Center In this chapter we consider orthogonal polygons, an important subclass of polygons that yield many interesting partitioning and art gallery theorems.
