The 11th International Workshop on Genetic Improvement @GECCO 2022

Financial District and Harbor, Boston


The 11th instalment of the GI workshop with next year Genetic and Evolutionary Computation Conference, GECCO 2022, which will take place in Boston on July 9-13.

Important Dates


Westley Weimer

We are happy to announce that Westley Weimer (University of Michigan, USA) will give the keynote speech in GI@GECCO 2022.

Prof. Westley Weimer received his PhD from the University of California at Berkeley. His research interests include reducing the costs associated with software development at scale (particularly through automated program repair) as well as program analysis, formal verification, and human linguistic and visual interaction with software. He is a senior member of the Association for Computing Machinery and his work has led to over fifteen thousand citations and several awards, including three ‘Humies’ and ICSE 2019 Most Influential paper for his work on using Genetic Improvement for bug fixing.

Call For Submissions [pdf]

We invite submissions that discuss recent developments in all areas of research on, and applications of, Genetic Improvement. The International Workshop on Genetic Improvement is the premier workshop in the field and provides an opportunity for researchers interested in automated program repair and software optimisation to disseminate their work, exchange ideas, and discover new research directions. Topics of interest include both the theory and practice of Genetic Improvement. Applications of GI include, but are not limited to:

We invite submissions of two paper types:

Detailed formatting instructions for authors are listed here.
We encourage authors to submit early and in-progress work. The workshop emphasises interaction and discussion.

These papers will be reviewed in a double-blind manner.
All accepted papers must be presented at GI-2022 and will appear in the GECCO companion volume.

Workshop Chairs

Bobby R. Bruce

Bobby Bruce is a Project Scientist at UC Davis where he primarily works on the gem5 computer architecture simulator. Prior to UC Davis, Bobby carried out research into the automatic optimization of Java bytecode at UCLA. His research interests are centred around Search-based Software Engineering, and its application to improving software performance.

Vesna Nowack

Vesna Nowack. Since she gained her PhD in Software Engineering in 2016 from the Universitat Politecnica de Catalunya in Barcelona, she has conducted research in supercomputing (Spain) and taught robotics in Germany. Her recent research has been on APR in the UK, including 12 months with Bloomberg (London) published this summer as “On the Introduction of Automatic Program Repair in Bloomberg” by IEEE Software. She is now a Senior Research Assistant at Lancaster University where she continues her work on using GI to automatically fix bugs.

Aymeric Blot

Aymeric Blot is a Research Associate conducting research in genetic improvement at the CREST and SOLAR groups in University College London. He received in 2018 a doctorate from the University of Lille following work on automated algorithm design for multi-objective combinatorial optimisation. His research focuses on strengthening GI techniques using knowledge from automated machine learning, algorithm configuration, and evolutionary computation. He maintains and evolves the community website on genetic improvement.

Emily Winter

Emily Winter is a Senior Research Associate at Lancaster University, specialising in the human and socio-technical aspects of software engineering. She works on the Fixie Project: Exploiting Defect Prediction for Automatic Software Repair, investigating developer needs and preferences for how they interact with an Automatic Software Repair tool. As part of her research, she is seconded as a contractor to Bloomberg LP.

Bill Langdon

Bill Langdon has been working on GP since 1993. His PhD was the first book to be published in John Koza and Dave Goldberg's book series. He has previously run the GP track for GECCO 2001 and 2014 and was programme chair for GECCO 2002 having previously chaired EuroGP for 3 years. More recently he edited FOGA 2011 and run the computational intelligence on GPUs (CIGPU 2008—2012) and EvoPAR workshops. His books include A Field Guide to Genetic Programming, Foundations of Genetic Programming and Advances in Genetic Programming III. He also maintains the genetic programming bibliography. His current research uses GP to genetically improve existing software, CUDA, search based software engineering and Bioinformatics. He co-organised GI 2015, GI 2017, GI 2018, GI 2019, GI 2021 and the 2018 Genetic Improvement of Software Seminar at Dagstuhl.

Justyna Petke

Justyna Petke is a Principal Research Fellow and Proleptic Senior Lecturer (Associate Prof.), conducting research in genetic improvement. She has a doctorate in Computer Science from University of Oxford and is now at the Centre for Research on Evolution, Search and Testing (CREST) in University College London. She has published on applications of genetic improvement. Her work on the subject was awarded a Silver and a Gold ’Humie’ at GECCO 2014 and GECCO 2016 as well as an ACM SIGSOFT Distinguished Paper Award at ISSTA 2015. She was the PC co-Chair for the International Symposium on Search-Based Software Engineering in 2017. She currently serves on the editorial board of the Genetic Programming and Evolvable Machines journal.
