Helsinki February Workshop 2018:
Theory of Distributed Computing
Aalto University, Finland · Monday, 26 February – Friday, 2 March 2018
Helsinki February Workshop is an invite-only research workshop on the theory of distributed computing. We will focus on distributed graph algorithms, broadly interpreted. The field has been progressing very rapidly in the past couple of years, and among the main goals of the workshop will be:
- sharing information on the recently discovered techniques,
- finding out what are the possibilities and limitations of these new tools,
- identifying where precisely is the current boundary between known and unknown, and
- ideally, pushing the boundary at least a little bit further.
We will aim at doing new research, not just presenting old work.
The event is organised by the Distributed Algorithms group at Aalto University; the contact person is Jukka Suomela.
The workshop is sponsored by Helsinki Institute for Information Technology HIIT, a joint research institute of Aalto University and the University of Helsinki.

There is no registration fee. With the help of our sponsor, we will try to provide lunch and coffee, but the participants are expected to cover their own travel expenses.
We will use the following Slack workspace for instant messaging and announcements: feb2018.slack.com. All participants will receive invitations to this workspace.
We will try to start each day with some short presentations and discussions among all workshop participants. We will then go for lunch together, and after lunch we will continue discussions in smaller groups.
While we have planned some activities in advance, we are very flexible; feel free to do whatever makes most sense to you! You are encouraged to use the Slack forum to e.g. coordinate meetings.
All participants should prepare a short talk that, ideally, follows this format:
- A brief introduction to a big open question related to your own research interests. This can be somewhat open-ended and vague.
- Example: Understanding why we have not been able to design algorithms that find a maximal independent set in o(Δ) + O(log* n) rounds in the LOCAL model?
- One or more concrete, simplified problems that seems to be just slightly outside the reach of our current techniques. This would be ideally something that is precise, concrete, and easy to explain – and maybe a bit surprising that such a seemingly simple question is still open.
- Example: Can you find a maximal matching in o(d) rounds in d-regular bipartite graphs in the port-numbering model? In O(1) rounds?
- A brief explanation of why the current techniques do not seem to apply here, what has been already tried, and what is your conjecture.
The presentation itself should be short (say, 15 min), but we can use much more time after the talk for discussions. Presentation slides are not necessary; you can also give a whiteboard talk.
There will also be some longer guest lectures aimed at the general CS or TCS audience, either in the lecture series of our department, or in Helsinki Algorithms Seminar. More details are coming later.
The workshop starts on Monday, 26 February 2018, and ends on Friday, 2 March 2018.
A rough plan of our typical daily schedule is as follows:
- 9.00am: short presentations, discussions with all participants (coffee/tea available)
- Monday, Wednesday, Thursday, Friday: room T4
- Tuesday: room T5
- 12.30pm: lunch – we will try out various restaurants in our campus:
- 2.00pm: research meetings in smaller groups
See information for our visitors for hotel suggestions, information on local transportation and tickets, etc. Please ask us (e.g. on our Slack forum) if you need any help!
