#2375 closed feature request (rejected)

Implement ALPS with OS

Description

Combining ALPS with aspects of Offspring Selection could be very interesting.

Each layer would be more robust in terms of used operators (crossover, …) and painful configuration of different operators for each layer would not be necessary.

In addition, flexible layer sizes similar to a RAPGA would be interesting.

  • Resolution set to rejected
  • Status changed from accepted to closed

Closed ticket since Offspring-Selection ALPS has proven to be ineffective due to the combination of contrary approaches (squeezing existing genetic material vs streaming of new genetic material).
