add simplification rule for at(x, offset) = ""
Introducing j just postpones some rewrites that prevent useful simplifications. Z3 already uses common sub-expressions.
The example highlights some opportunities for simplification, noteworthy at(..) = "".
The example is solved in both versions after adding this simplification.
- AC completion which is exposed as an option to the new congruence closure core used roots of E-Graph which gets ordering of monomials out of sync.
- Added injective function handling to AC completion
- Move to model where all equations, also unit to unit are in completion
- throw in first level bound bodies into the E-graph to enable canonization on them.
@levnach - there are some additional warnings.
You could revert the change to std_vector or use usize() that I added to vector.h. Look at build logs from the pipelines or actions or figure out how to add a continuous AI script to fixup build warnings (I tried a few times earlier on but the features available to do this were not for laymen).
