Hi John,
I followed the SAT developments from the recent years, and merged future techniques into a minisat fork that is still capable of the old interface (2.2.0, not the latest MiniSat github state). Most SAT competition solvers do not come with a git history, so just using those is hard.
My solver lives here, and from a performance point of view it can compete with CaDiCaL and other top solvers from 2020.
The question is whether the future fork should stay as close to where MiniSat os today, or whether future developments should be taken into account. With MergeSat, I try the latter approach in a lazy way, i.e. by merging development of competition submissions, testing them and fixing implementation issues that arise when conbining different techniques.
Other variants like using the Glucose solver sith the same (2.2.0) interface might also be a good successor.
Best,
Norbert
