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.

Ore selection problem

There are currently 2 data files.
These data files are the two test problems used in the paper:
"An iterative constructive heuristic for the ore selection problem",
A.J. Richmond and J.E. Beasley, Journal of Heuristics, 
vol. 10, 2004, 153-167

The test problems are the files:
osp1.txt and osp2.txt

osp1 is of size 3Mb (approximately) and has format:
50 (X-direction) x 50 (Y-direction) grid representing 50m x 50m (2,500 locations)
100 simulations
250,000 data lines
cycles fastest on x, then y, and then simulation

osp2 is of size 15Mb (approximately) and has format:
260 (X-direction) x 300 (Y-direction) grid representing 260m x 300m (78,000 locations)
25 simulations
1,950,000 data lines
