||6197 - Concorde (defaults), using QSopt as an LP solver. The run was carried out on a single AMD Althlon 1900+ processor (1.6 GHz), in 38275.1 seconds, using 299 nodes in the branch-and-bound tree.
||6197 - Found during branching run by Lin-Kernighan heuristic.
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.
