Last change on this file since 13782 was 13470, checked in by abeham, 9 years ago

#2221:

  • implemented review comments
    • hid rng as private class, implemented djb2 hash function (hash function implementation may also change)
    • added missing probabilities
    • base class for instance providers
    • prebuild event events
    • build platforms
    • unit test will be removed on trunk integration
    • corrected assembly file version
    • distance calculator parameter was not hidden, can be changed by user, updates distance matrix
    • fixed performance problems (ouch!) also for estimated ptsp (inlined GetDistance method)
  • added moves (full evaluation) for analytical tsp
  • added local improvement operators for analytical ptsp
  • added recalculation of distance matrix when parameters change
  • still lots of other changes
