Changeset 12119 for branches/ALPS


Ignore:
Timestamp:
03/04/15 12:53:48 (10 years ago)
Author:

Message:

#2350

  • Created base class Alps which manages ALPS specific parameters, events and parameterization.
  • Created empty AlpsGeneticAlgorithm.
  • Removed code from AlpsGeneticAlgorithm because the base class handles this now.
  • Created AgingSchemeCalculator to separate calculating of the age-limits from the algorithms.
  • ShiftToRightMigrator does no longer implement IMigrator to avoid conflicts with IslandGA.
