Q22: What test data is available?

TSP DATA

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

OPERATIONAL RESEARCH DATA

Information about Operational Research test problems in a wide variety of areas can be obtained by emailing <o.rlibrary@ic.ac.uk> with the body of the email message being just the word "info". The files in OR-Library are also available via anonymous FTP from ftp://mscmga.ms.ic.ac.uk/pub/ A WWW page is also available at URL: http://mscmga.ms.ic.ac.uk/info.html Instructions on how to use OR-Library can be found in the file "paper.txt", or in the article: J.E.Beasley, "OR- Library: distributing test problems by electronic mail", Journal of the Operational Research Society 41(11) (1990) pp1069-1072.
