Description

Support NSLC in the ProximityArchive. This involves modifying the add method in particular to compute local competition as well as value. It should be noted that the NSLC paper does not specify how replacement should be handled in the archive -- it would seem that the authors only use a regular novelty search archive. We have decided to implement a rule where if the solution is not novel enough for addition, it shall be compared to its nearest neighbor and added if it exceeds the objective value of its nearest neighbor.

TODO

  • Add local_competition flag to ProximityArchive
  • Add tests

Status

  • I have read the guidelines in
    CONTRIBUTING.md
  • I have formatted my code using yapf
  • I have tested my code by running pytest
  • I have linted my code with pylint
  • I have added a one-line description of my change to the changelog in
    HISTORY.md
  • This PR is ready to go
