Myra B. Cohen

We are happy to announce that Myra B. Cohen (Iowa State University, USA) will give the keynote speech in GI@ICSE 20223.

Prof. Cohen is a full professor at Iowa State University (USA), where she holds the Lanh and Oanh Nguyen Chair in Software Engineering in the Department of Computer Science. She is head of Iowa State’s LaVA-Ops, Laboratory for Variability-Aware Assurance and Testing of Organic Programs. As well as genetic improvement, her research covers software testing of highly-configurable software, SBSE, applications of combinatorial designs (CIT), and the synergy between systems and synthetic biology and software engineering. She has served on many software engineering conferences, including this year as the Technical Briefings-track chair of ICSE 2023.

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:

The best paper and best presentation will be awarded during the workshop.

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

Papers must be submitted through the paper submission website:
These papers will be reviewed in a double-blind manner.
All accepted papers must be presented at the workshop.

Note that per the ICSE 2023 guidelines:

  1. The official publication date is the date the proceedings are made available in the ACM or IEEE Digital Libraries. This date may be up to two weeks prior to the first day of ICSE 2023. The official publication date affects the deadline for any patent filings related to published work.
  2. Purchases of additional pages in the proceedings is not allowed.

Funding Opportunity For Students

We will support up to 5 students by offering to partially reimburse (up to 200 GBP each) registration and travel costs for students whose work is accepted to the GI workshop. Priority will be given based on the student’s need and submission quality.

Students applying for a scholarship should submit a first-author regular paper to the workshop (up to 8 pages long) and plan to present their work in Melbourne in person. Moreover, their supervisor should send a one-paragraph note of recommendation to listing:

Workshop Chairs

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 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.

Markus Wagner

Markus Wagner is currently an Associate Professor at the University of Adelaide, and he will move to Monash University, Melbourne, Australia, in January 2023. He has organised two GI workshops and co-presented GI tutorials at ASE 2020, GECCO 2020 and 2021. This year he was general chair for ACM GECCO-2022 having previously served as Workshop Chair and Competition Chair. Within the IEEE CIS, he has chaired several education-related committees, where he also served as founding chair of two task forces.

Gabin An

Gabin An is a doctoral candidate at KAIST in South Korea, advised by Prof. Shin Yoo. Gabin’s work focuses on faster and more accurate bug assignments and, in close collaboration with industry, improving test suites. She is also behind PyGGI, a Python library for fast prototyping of GI techniques for multiple programming languages. Gabin served as the web chair for GI@ICSE 2020 and the GI workshop PC 2021-2022.

Aymeric Blot

Aymeric Blot is a Senior Lecturer in the Université du Littoral Côte d’Opale, Calais, France. Before that he was 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.

Justyna Petke

Justyna Petke is a Principal Research Fellow and Proleptic Associate Professor, conducting research in genetic improvement. She is at the Centre for Research on Evolution, Search and Testing at University College London. Her work on genetic improvement was awarded a Silver (GECCO 2014) and a Gold ’Humie’ (GECCO 2016) and 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 8 Genetic Improvement Workshops. She currently serves on the editorial board of the Empirical Software Engineering (EMSE), and Automated Software Engineering (ASE) journals.
