Our new version of Kissat dominated the main track of the SAT Competition 2024. It won three gold medals! Core techniques are clausal congruence closure (SAT'24), clausal equivalence sweeping (FMCAD'24) an efficient implementation of bounded variable addition (BVA) and revisiting vivification. https://lnkd.in/dXyQCgXY

I haven't really been tracking progress in SAT solving since I finished my PhD a few years ago, I have to admit. Looking at the graphs now, I can't help but notice that some things have changed and others have not. What has changed are the names of the SAT solvers. Coming from the golden age of MiniSat, none of this year's competitors ring a bell for me. What hasn't changed is Armin Biere winning the competition. That seems to be a fundamental law of SAT solving. Props not just for this year's win but for the consistency in doing so over the years.

Hi Armin Biere, congratulations! It's been years since I last checked what new SAT solvers are exactly doing to keep improving (the last one I understood thoroughly is minisat I think); but when I saw this 2024 graph I was impressed by how much of a leap you can still achieve in just 1 year, after (at least) a quarter of a century of continuous improvements. I immediately had to go read the abstracts and main results of those 4 or 5 papers (of yours, mostly) that present the techniques that give you the boost; (and of course, when reading those articles, as any self-respecting (ex) researcher in automated reasoning, I couldn't help but thinking.... of course!, this is a good idea, this is bound to work ... 😎). It really looks like it's still fun and approachable to work on SAT!! It's also refreshing to see such a principled approach to automated reasoning in action, in the age of generative AI & LLMs and every kid trying everything by mixing whatever has "transformer" in its name to do some "correct reasoning"... 🤗 Kudos to you and to your group
