Abstract

We consider the problem of packing two-dimensional rectangles into the minimum number of unit squares, when 90^@? rotations are allowed. Our main contribution is a polynomial-time algorithm for packing rectangles into at most OPT bins whose sides have length (1+@e), for any positive @e. Additionally, we show near-optimal packing results for a number of related packing problems.
