The 33rd BCTCS will be hosted by the School of Computer Science, University of St Andrews, from the 26th to the 28th of April 2017. The purpose of BCTCS is to provide a forum in which researchers in theoretical computer science can meet, present research findings, and discuss developments in the field. It also aims to provide an environment in which PhD students can gain experience in presenting their work, and benefit from contact with established researchers.

The scope of the colloquium includes all aspects of theoretical computer science, including algorithms, complexity, cryptography, formal methods, game theory, machine learning, languages, logics and quantum computation. Both computer scientists and mathematicians are welcome to attend, as are participants from outside of the UK.

This year the colloquium will feature the following invited speakers

LMS Keynote Lecture in Discrete Mathematics
Professor László Babai, University of Chicago

Confirmed Speakers
Perdita Stevens, University of Edinburgh
Conor McBride, University of Strathclyde
Felix Fischer, University of Glasgow
Edwin Brady, University of St Andrews
Mehrnoosh Sadrzadeh, Queen Mary University of London

Registration is *now open*, and you can find more information at https://bctcs2017.cs.st-andrews.ac.uk/

PhD students are especially encouraged to offer a talk.

As an additional event, there will be a Scottish Combinatorics Meeting at the School of Mathematics in St Andrews on the 24th and 25th of April. If you would like to take part in the meeting, please contact the organisers directly.

The organisers hope to welcome you to St Andrews in April.
