Also you can run Concorde over the Internet by taking advantage of the NEOS Server: www.neos-server.org Click on "NEOS Solvers" and look under Combinatorial Optimization and Integer Programming. You specify an appropriate Concorde input file to be uploaded from your computer, and the optimal tour is displayed in your browser. (There is also an API for making submissions from your own program.) I mention this here because one can also run GLPK through NEOS, saving the time of installing it locally. It is hosted for NEOS at the Univ of Wisconsin currently only with GAMS input, but if there's interest I think they could be persuaded to put up versions with input in MathProg and some low-level formats like MPS and LP.
