November2022 ShinYoo Preface MessagefromtheProgramChairs On behalf of the SSBSE 2022 Program Committee, it is our pleasure to present the proceedings of the 14th International Symposium on Search-Based Software Engineering. Search-Based Software Engineering (SBSE) is a research area focused ontheformulationofsoftwareengineeringproblemsassearchproblems,andthesubse- quentuseofcomplexheuristictechniquestoattainoptimalsolutionstosuchproblems. A wealth of engineering challenges – from test generation to design refactoring and process organization – can be solved efficiently through the application of automated optimization techniques. SBSE is a growing field – sitting at the crossroads between AI,machinelearning,andsoftwareengineering–andSBSEtechniqueshavebegunto attainhuman-competitiveresults.SSBSE2022continuedthestrongtraditionofbring- ing together the international SBSE community in an annual event to discuss and to celebrateprogressinthefield. Thisyear,SSBSEhadatotalof15validsubmissionsinalltracks.Wewouldlike to thank all authors and reviewers for their efforts in making the conference program interesting and broad. Specifically, we received 11 papers to the Research track, one paper to the Challenge track, and three to the RENE/NIER track. At the end of the double-blindreviewprocess,whereeachsubmittedpaperwasreviewedbyatleastthree SBSE researchers, six papers were accepted to the Research track and one paper was acceptedtotheChallengetrackandtheRENE/NIERtracks. The program included two keynote talks, one from Lionel Briand, who reported hisexperiencesandlessonslearnedinapplyingsearch-basedsolutionstotestandana- lyze ML-enabled systems, and one from Justyna Petke, who reported her experience andresearchingeneticallyimprovingsoftwaresystems.Additionally,theprogramalso includedatutorialonguidelinesforevaluatingmulti-objectiveSBSEapproachesfrom MiqingLiandTaoChen.Finally,theSSBSEcommunityhadtheopportunitytodiscuss thefutureoftheSearch-BasedSoftwareEngineeringareawithoutstandingresearchers fromthefield.
