Call for Papers: Thirtieth Anniversary of Genetic Programming: On the Programming of Computers by Means of Natural Selection

In 1992, John R. Koza published his first book on Genetic Programming (GP): "Genetic Programming: On the Programming of Computers by Means of Natural Selection" [1]. This ground-breaking book paved the way for the establishment of a new field of study. It influenced the work of thousands of researchers and practitioners worldwide, many of whom aimed to continue the exploration, formalization and improvement of the original formulation of GP and/or to apply GP to challenging problems.  

We aim to celebrate the 30th anniversary of [1] with a special issue that focuses on the multiple impacts that the book had, and is still having, on the GP field. We hope that the special issue will illustrate many of the ways in which the ideas proposed by Koza in [1] have influenced and are still influencing the GP community. 

[1] Koza, J. R. (1992). Genetic Programming: On the Programming of Computers by Means of Natural Selection. Cambridge, MA, USA: MIT Press. ISBN: 0-262-11170-5


We are open to a broad range of submissions that, in various ways, help us better understand the impact of [1] on the GP community. Submissions that would be welcomed might for example present: 

  • High quality review articles of [1] and of subsequent books or other types of publications, that may include a deep discussion of the relationship, similarities and differences with [1].
  • Discussions of ways in which current techniques and practices are similar to or different from those recommended in [1], and the ways in which the methods presented in [1] have evolved towards more modern and effective methods.
  • Challenges that [1] regarded as open, and the extent to which they are now completely fulfilled or that still constitute open issues for the GP field. 
  • Ground-breaking ideas that were proposed in [1] and that have inspired research in the past, or may inspire new research in the future.
  • Ideas in [1] that have received little attention to date, which might be beneficial to revisit.
  • Works that deal with the impact that [1] has had in applied domains, exploring and/or surveying the achievements and limits of the methods and ideas proposed in [1] for solving real-world problems.
  • Applications that directly build on the techniques described in [1] and are able to achieve human-competitive results.


  • Submission deadline: 30 July 2022
  • Initial reviews: 15 October 2022
  • Resubmissions: 10 December 2023
  • Final notifications: 10 February 2023
