The 10th International Workshop on Genetic Improvement @ICSE 2021

Plaza de Cibeles, Madrid

Important Dates

Due to the COVID-19 pandemic GI@ICSE 2021 will be held as a completely virtual event.

The GI@ICSE 2021 submission deadline has been extended to 19th Jan (AoE).


Stephanie Forrest

We are happy to announce that Stephanie Forrest (Arizona State University) will give the keynote speech in GI@ICSE 2021.

Prof. Stephanie Forrest works at Arizona State University, where she directs the Biodesign Center for Biocomputation, Security and Society in the School of Computing, Informatics and Decision Sciences Engineering (CIDSE). Forrest studies the biology of computation and the computation of biology, including work on computational immunology, computer security, automated software repair, evolutionary computation, and biological modeling.

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:

Research & Position Papers

We invite submissions of two paper types:

We encourage authors to submit early and in-progress work. The workshop emphasises interaction and discussion.

All papers should be submitted via HotCRP:

These papers will be reviewed in a double-blind manner. PDFs should therefore be anonymized prior to submission. The IEEE conference format should be utilized with title in 24pt font and full text in 10pt type. LaTeX users must use \documentclass[10pt,conference]{IEEEtran} without including the compsoc or compsocconf options). Please check the ICSE 2021 submission information page for more information on paper formatting.

Please also consult the ICSE 2021 Q&A page on double blind submissions.

All accepted papers must be presented at GI-2021 and will appear in the ICSE workshops volume.

Workshop Chairs

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 also organised six Genetic Improvement Workshops. She currently serves on the editorial board of the Genetic Programming and Evolvable Machines journal.

Bobby R. Bruce

Bobby Bruce is a Postdoctoral Scholar 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.

Yu Huang

Yu Huang is a PhD candidate at the University of Michigan, Ann Arbor. Her research includes applying GI-based automated program repair (APR) techniques in embedded systems and human factors in software automation with a focus on human bias against automated tools in code review. She has served as the organizer for multiple Diversity, Equivalence and Inclusion events hosted at University of Michigan. She was also in charge of the social media for GI 2020 to advertise the event and connect researchers and practitioners in the community. Currently she is serving as the Social Media Chair for GI 2021.

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.

Westley Weimer

Westley Weimer is a Professor at the University of Michigan He 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 eleven thousand citations and several awards, including three ‘Humies’ and ICSE 2019 Most Influential paper for his work on using Genetic Improvement for bug fixing. He also organised five Genetic Improvement workshops.
