OR-Library is a collection of test data sets for a variety of OR problems.

A full list of the test data sets available in OR-Library can be found here.

Constrained guillotine cutting

There are currently 3 data files.

These data files are the 3 test problems from Table 2 of
N.Christofides and C.Whitlock "An algorithm for
two-dimensional cutting problems" Operations Research 25 (1977)
30-44.

Test problems 1, ..., 3 from Table 2 of that paper are
available in files cgcut1, ..., cgcut3 respectively.

The format of these data files is:
number of pieces (m)
length, width for the stock rectangle
for each piece i (i=1,...,m): length, width, maximum number
of pieces of that type that can be cut from the stock
rectangle, value of the piece

The value of the optimal solution for each of these data files
is given in the above paper.

The entire set of files is of size 2Kb (approximately).
