The full source code to the Concorde network optimization
package, as well as executables for various platforms, and a Windows graphical user interface to Concorde's traveling salesman solver are available for academic research use; for other uses,
contact William Cook
for licensing options.
The Concorde source code is distributed as a gzipped tar file. To install the code follow the instructions given in the README and Installation Guide.
|gzipped tar file||version date|
|Concorde-03.12.19||Dec 19, 2003||ANSI C Code as gzipped tar file|
|Concorde-99.12.15||Dec 15, 1999||Older code, no longer supported|

Executable versions of Concorde and Linkern are available for Linux, Solaris, and Windows/Cygwin. Concorde is the cutting-plane-based exact TSP solver (using the QSopt LP solver) and Linkern is an implementation of the Chained-Lin-Kernighan heuristic for the TSP. The executable codes are given as gzipped files. The Windows/Cygwin codes will run under Windows 98/ME/NT/2000/XP if at least the minimal version of the Cygwin environment is installed.
