Box Stacking Problem

Given a set of rectangular 3D boxes, create a stack of boxes which is as tall as possible. A box can be placed on top of another box if the dimensions of the 2D base of the lower box are each strictly larger than those of the 2D base of the higher box. Multiple instances …

Maximum Length Snake Sequence
