We are happy to announce that Westley Weimer (University of Michigan, USA) will give the keynote speech in GI@GECCO 2022: From Deep Learning to Human Judgments: Lessons for Genetic Improvement.
Many new techniques and evaluation approaches are being considered in subfields like automated program repair or manual program improvement, but they have not yet translated to popular success in the subfield of Genetic Improvement. For example, automated program repair researchers are increasingly considering deep neural network or neural machine translation approaches to fix defects – approaches which may seem, at first glance, to be incompatible with genetic methods. Similarly, there has been an increasing use of advanced measurements, such as eye tracking or medical imaging, or experimental designs, such as the use of deception, in the evaluation of bug-fixing patches – but those evaluations are not as common for genetic improvement. This keynote address summarizes some recent techniques, placing them in a GI context and arguing that many of these techniques are compatible with a continuous notion of genetic improvement (as opposed to a discrete notion of program repair). This keynote also summarizes recent evaluations and their use in the field, as well as lessons that can be learned from industrial deployments (e.g., from Facebook to Fujitsu to Bloomberg) about human trust and acceptability. It concludes with a call to arms about the potential impact of Genetic Improvement.
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:
- Improve efficiency
- Decrease memory consumption
- Decrease energy consumption
- Transplant new functionality
- Specialise software
- Translate between programming languages
- Generate multiple versions of software
- Repair bugs
We invite submissions of two paper types:
- Research papers (eight page limit, excluding references)
- Position papers (two page limit, including references)
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: https://ssl.linklings.net/conferences/gecco/
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.
