Given a simple polygonal region P and a finite set S of points in P, we want to cover S with the minimum number of disks contained in P. In general, such covering problems tend to be hard, but this one was debunked to be polynomial time solvable by Katz and Morgenstern (2009). We will discuss the structure behind the solution. Be prepared for the appearance of the medial axis and chordal graphs.
