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 43rd CREST Open Workshop - Hyper-Heuristics for Software Engineering

Date:  26th and 27th October 2015


Search Based Software Engineering (SBSE) has proved extremely attractive to software engineers, because it handles messy conflicting multi-objective problems and copes well with noise and with partial and contradictory information. Although SBSE has proved very widely applicable and generalisable, many software engineers now find themselves bewildered by the enormous variety of potential computational search algorithms available to them. For many software engineering problems, generalist algorithms that perform acceptably well (across a wide range of problem instances) would be considerably preferable to a set of specific algorithms, each of which has to be carefully selected and tuned to the particular problem in hand, even if such careful tuning could outperform the generalist. Hyper-heuristics offer such a generalist solution, able to learn and adapt to the problem in hand, and therefore they have become increasingly attractive to software engineers. This workshop will bring together researchers working on hyper-heuristics and SBSE, seeking to stimulate wider and deeper collaboration, and to map out an agenda for Hyper-Heuristic Software Engineering. Funding for the workshop is provided by the EPSRC project DAASE (


The 44th CREST Open Workshop - Predictive Modelling for Software Engineering

Date:  23rd and 24th November 2015

Venue: Engineering Front Executive Suite, Roberts Building, UCL (Directions, or 'C5' on the map here, or Find it on Google maps.)


Predictive modelling is very important in software engineering, and has been used, inter alia, to predict project costs, and the faultiness (or otherwise) of software components. Adaptivity is also important to allow software systems to maintain performance and service levels within dynamically changing environments. This workshop will bring together researchers working on search based optimisation (SBSE) for dynamic adaptivity with researchers working on predictive modelling. This will allow us to explore the possible applications of predictive modelling to support enhanced software and activity. Funding for the workshop is provided by the EPSRC project DAASE (

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.
