Chapter 1 Introduction

This is the supplemental material associated with our 2021 GPTP contribution entitled, An Exploration of Exploration: Measuring the ability of lexicase selection to find obscure pathways. Preprint forthcoming.

1.1 About our supplemental material

This supplemental material is hosted on GitHub using GitHub pages. The source code and configuration files used to generate this supplemental material can be found in this GitHub repository. We compiled our data analyses and supplemental documentation into this nifty web-accessible book using bookdown.

Our supplemental material includes the following:

  • Data availability (Section 2)
  • Guide for running our software (Section 3)
  • Experiment analyses:
    • Tournament selection versus lexicase selection (Section 4)
    • Lexicase selection at a range of diagnostic cardinalities (Section 5)
    • Increasing population size versus increasing generations (Section 6)
    • Epsilon lexicase selection (Section 7)
    • Down-sampled lexicase selection (Section 8)
      • Down-sampled lexicase selection (increased population size) (Section 9)
    • Cohort lexicase selection (Section 10)
      • Cohort lexicase selection (increased population size) (Section 11)
    • Novelty-lexicase selection (Section 13)
