Implement Algorithms: SASEGASA

Reported by: abeham Owned by: abeham
Priority: high Milestone: HeuristicLab 3.3.0
Component: Algorithms.OffspringSelectionGeneticAlgorithm Version: 3.3
Keywords: Cc:

Description (last modified by abeham)

The attached engine is an example of how to model a SASEGASA algorithm with existing and new programmable operators in HL3.2.

The engine features all of the SASEGASA attributes of HL1 except attenuation. The details are not currently checked with the code in HL1/HL2. Particularly before implementing the algorithm one needs to:

  • Check the rearrangement procedure
  • Check if selection pressure abort condition for a village is selPress '>' or '>=' maxSelPress

The engine can be executed, it will (likely) solve the ch130 TSP
