I would very much like to merge :) I have updated the description. I think that actually all the solvers get updated. |
This updates the solvers to the following versions: * Bitwuzla 0.8.2 * cvc5 1.3.0 * z3 4.15.2 Bitwuzla 0.8.2 now uses abstraction by default. On my simplified vat contract, solving was order of magnitude faster than with Bitwuzla 0.7.0.
Bitwuzla with abstraction can solve many previously challengin queries pretty fast now. We update the example to test solver timeout to a more challenging one. This new one is basically a factorization of a large number, i.e., expressing it as a multiplication of two primes.

I actually had to update the example where we test SMT solver timeout, because the new bitwuzla solved the previous one under the 1 second timeout on my laptop. |

Description
This updates the solvers to the following versions:
Bitwuzla 0.8.2 now uses abstraction by default.
On my simplified vat contract, solving was order of magnitude faster
than with Bitwuzla 0.7.0.
Additionally, the new Bitwuzla comes with it's own Windows release, so we can remove our own Bitwuzla build from our CI pipeline.
