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.
There are currently 12 data files. Problem sets Random & Perfect are the first five data sets from Tables 7 and 8 respectively of J Mingers & FA O'Brien 'Creating student groups with similar characteristics: a heuristic approach', OMEGA, 23 (1995), 313-321. File eppstud93 is the 1993 data set from Table 8 of that paper. Data file eppresid is the data file associated with Tables 10 & 11 of FA O'Brien & J Mingers 'A heuristic algorithm for the equitable partitioning problem', OMEGA, 25 (1997) 215-223.
These data files have been contributed by FA O'Brien (email email@example.com) The format of all data files as follows: Each line of a data set represents the attributes of an individual. The objective of equitable partitioning is to organise the individuals into groups such that each attribute is evenly distributed amongst the groups. Problem Set Files Random epprandom1,...,epprandom5 Perfect eppperf1,...,eppperf5 The entire set of files is of size 11Kb (approximately).
