CREST Open Workshop (COW)


Welcome to the CREST Open Workshop (COW)

The CREST Open Workshop programme consists of a series of informal monthly workshops organised by the CREST Centre (Centre for Research on Evolution Search & Testing) at UCL. There will be no call for papers.

The aim of this regular monthly workshop is to bring together researchers and practitioners working on a topic with a focus on discussion and interaction and with no formal proceedings. We create the program largely by invitation and then issue a call of participation. Outstanding researchers from all over the world are invited to present their original and significant work and the level of international attendance at the workshops is also very good.


The 45th CREST Open workshop  - Genetic Improvement 

Date: 25th and 26th January 2016


Genetic Improvement (GI) aims to find improved versions of existing programs that retain some partial semantics of the original (and possibly some of its syntax too). GI has been used to improve many system aspects such as its correctness (through bug fixing) and resource consumption such as time, memory and energy. It has also been used for other kinds of improvement such as specialising and porting. Many and varied techniques have proved successful at improving programs, such as loop perforation, genetic programming, guided random search, transplantation and constraint-based synthesis. This workshop will bring together researchers working on Search Based Software Engineering (SBSE), Program Synthesis, Genetic Programming, Program Analysis and Manipulation. We will explore the possible applications, development of techniques, evaluation and theory. Funding for the workshop is provided by the EPSRC projects DAASE ( and GGGP.

Downloadable Resources from Previous Workshops

We put a lot of effort into fully archiving materials from the workshops as a resource for the communities we serve. For instance, on the website you will find slides of talks, videos of many of the presentations (where the presenter kindly gave us permission to make this available). We do not videotape the discussions as we feel that this may have a harmful effect on the desired interaction and free exchange of ideas.

A list of upcoming workshops can be found here. Information about previous workshops as well as videos and slides are available here.


Free Registration

Through the kind support of the EPSRC in the form of a platform grant, we have funding to support the workshops, so registration is free but required.
