Abstract

In the strip packing problem the goal is to pack a set of rectangles into a vertical strip so as to minimize the total height of the strip needed. We consider a modified version of the strip packing problem. In this version it is allowed to change the form of the rectangles by lengthening them, keeping the area fixed. We introduce online algorithms to solve this modified problem. Moreover a lower bound is presented, as well.
