Yesterday, on the 4th of August I gave an invited talk on Maximum Satisfiability at the “25 years of SAT” celebratory session of the 2022 SAT conference at Haifa in Israel. Mine was one of 5 talks, the others were given by Alexander Nadel, Armin Biere, Olaf Beyersdorff and Marijn Heule.
I would like to thank the session organiser, Prof. Jakob Nordström for the invite. I am honoured to have been considered together with such established researchers of the field.
In may this year I visited Prof. Bart Bogaerts at the Vrije Universiteit Brussel.. During the two week visit we talked about possible connections between our research. We were also joined by Jakob Nordström, his student Andy Oertel, and Ciaran McCreesh. At the end of the visit, I also spent a day in Delft talking to Emir Demirović.
I’d like to thank Bart for hosting the visit and everyone else for the interesting discussions. I am looking forward to potential further collaboration.
The doctoral program is a full day even at the conference. The goal is to gather early-career (student) researchers in order to discuss ongoing research in a relaxed atmosphere. Additionally the DP aimed to provide opportunities for students to interact with more experienced researchers.
This year, the DP was a full day event held om 25th of October, the workshop day of the main conference. We had nine submissions from students. The program consisted of a discussion of the reviews submitted by the participants, two sessions for the participants to present their own work, and a panel discussion on presenting work with more senior researchers. The panelists were: Professor Christine Solnon from INSA de Lyon Professor Tias Guns from KU Leuven Professor Susanna de Rezende from the Czech Academy of Sciences, Prague an Royal Society Research Fellow and Reader Christopher Jefferson from University of St. Andrews. The program concluded with a social session were we played codenames with the participants.
The videos of the contributions to the DP (including the panel) can be found on youtube (below). The submissions themselves can be found on Google Drive.
I would like to express my sincerest gratitude to everyone who contributed to the doctoral program, including all of the authors, the panelists and everyone who agreed to be on the program committee and provide the students with helpful comments.
While the DP is over, the conference itself is still going on. Two of my papers will still be presented today and the last one on Friday. If you’re interested you should definitely check it out, more info on the conference webpage.
During this year I have been a part of the steering group of a project called UniJunior. The aim of the project is to increase the curiosity of children in elementary school towards science and research by organising a series of interdisciplinary workshops in Swedish once per month during the fall and spring of 2021-2022. The project especially targets kids coming from non-academic homes. It is funded by Svenska Kulturfonden and Stiftelsen Brita Maria Renlunds minne.
Last Saturday the project kicked off with a workshop on colors, a workshop planned mainly be me and Christoffer Fridlund. The kids got to learn about what kind of a role color plays in different chemical reactions, how rainbows are formed by light refraction and how computers represent color as numbers. I thought the whole things went really well and—based on the feedback we collected—so did the kids!
I would especially like to thank Martina, Eva and Jim for planning, organising, and running the workshop with me and the ChemistryLab Gadolin for lending their premises and suplies for the workshop. I would also like to express my gratitude to everyone in the steering group of UniJunior, including its chair Prof. Gunilla Holm.
I am happy to let you know that I had three papers accepted at CP 2021. More details on them (as well as the full versions) can be found on on the publications page on these webpages. I would like to thank all my co-authors, especially Pavel and Hannes whose first papers these are. See you at the conference in October!
These papers also mark the beginning of my very own Academy of Finland project! I am looking forward to developing new optimisation algorithms that combine the strengths and weaknesses of many different paradigms and also work incrementally.
The results of the 2021 MaxSAT Evaluation were just announced at the 2021 SAT conference (by me :)). My solver Loandra performed very well, taking first place in the weighted 300s track and fourth in all other tracks. The source code of that version of Loandra is already available at the evaluation website and in its repository.
I would like to thank my co-organizers of the Evaluation and the organizers of the SAT conference. I am looking forward to taking a closer look at the results.
Today I received the very pleasant news of having been granted funding for my project “Next-generation Trustworthy Constraint Optimisation” from the Academy of Finland, My proposal was one of the 44 post-doctoral projects that were granted funding (11% of all applications). My term as an Academy postdoctoral researcher will start this fall and continue until 2024. The full list of funded proposals can be found here.
I would like to express my sincerest gratitude toward the Academy. I am looking forward to the opportunity of realizing my (very cool) research plan!
A week ago I gave the second talk at the Simons Institute, this time at the Theoretical Foundations of SAT/SMT Solving seminar. The event webpage can be found here. I had the opportunity to talk about my work on preprocessing for Maximum Satisfiability, covering work done both during and after the preprocessing.
I would again like to thank Marjin Heule for considering me as a speaker for the event. Next time you can hear me speak is at Jakob Nordströms video seminars on the 4.6. I will talk about Abstract Cores in the IHS algorithm for MaxSAT, covering my recent paper from SAT 2020. Looking forward to seeing you there!
