Instance Set

These instances are the test problems used by A. M. Del Valle, T. A. Queiroz, E. C. Xavier and F. K. Miyazawa for the Two-dimensional Irregular Unconstrained Knapsack Problem [1]:

Inside the pointed .zip file, there are two subfolders:

  • The subfolder ‘Items’ has the data files with the polygon that corresponds to each item into the respective instance;
  • The subfolder ‘NFPS’ has the information required by each instance for the calculus of the No-Fit-Polygons.

More detailed information about each instance can be found here.
