Lexicase Paper Rejection

  • Some possible additions ideas:
    • Investigate how much of pop is let around after each step of lexicase
    • time runs for this paper
  • Lexicase speedup idea: use a lexicase comparator, and then find optimum in population
    • To do this, would need a lexicase comparator that takes 2 individuals (or error vectors) as well as a test case ordering, and returns the individual with better initial cases based on the ordering
    • Then, you can use the comparator to find the “max” (or “min”) of the population – basically, use it with reduce to find best individual for that ordering
    • We should include this as a possibility in paper, but probably not implement it.
  • Thoughts on niching/fitness sharing:
    • We should definitely enhance our discussion with related techniques, but not necessarily implement and compare with them
    • We should clarify how lexicase is different
    • If we find one option that is common and simple, we could try it out if we have time.
