I seem to recall this sort of tiling problem figuring crucially in a proof of a circuit complexity lower-bound; we used two different numbers, with and without the requirement that the rectangles be non- overlapping. Unfortunately, I can't seem to find my notes from Mike Saks' class, in which we did this. -- Stephen Bloch sbloch@math.ucsd.edu -- Send compilers articles to compilers@iecc.cambridge.ma.us or {ima | spdcc | world}!iecc!compilers.
