要旨:
A strategy of merging several traveling salesman tours
into a better tour, called ACC (Alternating Cycles Contribution)
is introduced. Two algorithms embodying this strategy for
geometric instances is
implemented and used to enhance Helsgaun's implementaton
of his variant of the Lin-Kernighan heuristic. Experiments
on the large instances in TSPLIB show that a significant
improvement of performance is obtained.
These algorithms were used in September 2002 to find a
new best tour for the largest instance pla85900
in TSPLIB.
