   abstract =	"We study the problem of covering a simple
		 orthogonal polygon with a minimum number of (possibly
		 overlapping) squares, all internal to the polygon. The problem
		 has applications in VLSI mask generation, incremental update
		 of raster displays, and image compression. We give a linear
		 time algorithm for covering a simple polygon, specified by its
		 vertices, with squares. Covering with similar rectangles
		 (having a given x/y ratio) is an equivalent problem.",
