system-solving challenges

[D. J. Bernstein]

And now for something completely different from ideal lattices... :-)

https://www.mqchallenge.org opened at the beginning of the month. The
authors announced this at NIST's post-quantum workshop last week:

The next talk also looked interesting for cryptanalysts, and included an
announcement that a few of the MQ challenges have already been solved:

My impression was that there's now some state-of-the-art system-solving
software (GBLA), which is a welcome change from the previous situation
of hard-to-verify papers using proprietary software.
