This verifies a bit hack from here:
https://en.wikipedia.org/wiki/Lehmer_random_number_generator#Sample_C99_code
I previously ran the SMTLIB equivalent this with Bitwuzla in my crypto
class and got the following numbers:
- 22s with Bitwuzla
- Z3 and CVC5 don't yet terminate after > 2min
Now with`bv_decide` the overall timing is 33.7s, consisting of:
- 5s of checking the LRAT cert
- 5s of trimming the LRAT cert from 800k to 300k proof steps
- remainder actual solving time
So running `bv_decide` like a normal SMT solver without verifying the
result of the SAT solver would yield approximately ~24s.
