% Rectangles aligned with the axes need to be place in the smallest
% possible bounding box. No overlap is allowed. Each rectangle to be placed
% can be reconfigured, within some limits.
% In the current problem, 60 rectangles are to be place. We are given 2
% acyclic graphs H and V (for horizontal and vertical) that specify the
% relative positioning constraints of those rectangles.
% We are also given minimal areas for the rectangles and aspect ratio
% constraints
