Instance Set

These instances are the test problems used by T. A. Queiroz, F. K. Miyazawa, Y. Wakabayashi and E. C. Xavier for the Three-dimensional Unbounded Knapsack Problem [1]:

• Instances: 3duk_knapsack[.zip] (212KB).

The format of each data file is:

        N               number of box types
        L W H           container length, width and height
        l w h           (N lines, one line for each box type
        .               .
        .               .
        .               .)
        instance_name   instance name

The line for each box type contains 3 numbers: box length (l), box width (w), box height (h).

In all these instances the value of each item is precisely its volume (and it was omitted of the instance).
