To allow for easy access to the problem data many of the instances are available not only in our XML based format but in a very simple ORLib-based format.
Each of these files consists of integers seperated by whitespace. Each file starts with the number of problems cotained in it. For each problem the number of containers and the dimensions of each container is given. The list of containers is followed by the number of boxes. For each box the width, height, cost, minimal and maximal count are given.
