Báo cáo toán học: " Efficient packing of unit squares in a square" ppt
... Introduction. Erd˝os and Graham [1] initiated the study of packing unit squares in a square by demon- strating that non-trivial packings can result in a wasted area that is surprisingly small. For a square with ... unit squares, so that it remains to show that mn + 1 unit squares can be packed into R. We first partition R into a parallelogram P and two trapezia T , T of equal siz...
