Some Results

The following table shows some of the results obtained by some of the heuristics (see the description below) in a 2 hour experiment, running on a cluster of Intel E5-2470 processor, 8 Cores, 2.3 Ghz and 32Gb or RAM memory:

  • (*)In this case, neighborhoods for the VMND heuristic were generated automatically, this is, based on the Variable cluster described in the User's Guide.
