Executable Programs
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.
