2Tools for generating 2d bin packing instances. 

3 

4We want to generate instances of the two-dimensional bin packing problem. 

5These instances should have some pre-defined characteristics, e.g., width and 

6height of the bins, number of items to pack, lower bound/optimal number of 

7bins required by any solution, and so on. 

8 

9At the same time, the instances should be hard. 

10 

11We treat this whole thing as an optimization problem. Here, given are the 

12pre-defined instance characteristics and the goal is to find instances that 

13are hard to solve.
