There is a TSP library (TSPLIB) available which has many solved and semi-solved TSPs and different variants. The library is maintained by Gerhard Reinelt <reinelt@ares.iwr.Uni-Heidelberg.de>. It is available from various FTP sites, including: ftp://softlib.cs.rice.edu/pub/tsplib/tsblib.tar

The following is a list of some of the topics covered.

William Spears <spears@aic.nrl.navy.mil> maintains a WWW page titled: *Test Functions
for Evolutionary Algorithms* which contians links to various sources of test functions.

ENCORE
(see Q15.3) also contains some test data. See directories under **/etc/data/**
