Folder structure:

BPP: contains the 3DBPP codes
BSP: contains the BSP codes without order splitting
BSP_2bin: contains the B&R with order splitting into 2 bins
datasets_xml: contains all data files as xml files


General remarks:
----------------------
Except of the case study, all results used unused space as objective function.
To reproduce the results with cost functions, use the a different file for packages: packages_UPS instead of packages with the reader function readDataPrices
Moreover, the costs for filling material depend on the unused space and need to be calculated in the preprocessing when unused space is calculated within the code.
The costs for unused space are 0.000007725
They occur in all objective functions and need to be adjusted in the preprocessing and in the MILPs.
