||7219 - Best of 10 runs of LKH, each with n trials. Total running time 2276 seconds on an AMD Althlon 1900+ processor (1.6 GHz).
||7219 - Concorde (default settings) using QSopt as an LP solver. The run was carried out on a Athlon 1900+, in 1353264 seconds, using 3141 nodes in the branch-and-bound-tree.
1. Concorde is our linear-programming based TSP solver.
2. linkern is an implementation of Martin, Otto, and Felten's Chained Lin-Kernighan heuristic. It is included in the Concorde code.
3. LKH is Keld Helsgaun's powerful implementation of the Lin-Kernighan heuristic.
