Online Z3 Guide
microsoft.github.ioI like Z3 a lot. I think it's criminally underappreciated and underused. Here is a fairly interesting use I put it to a few years ago:

Slightly more complicated than the toy examples shown in the documentation above, and hints at one of the real world use cases for Z3 - red teaming cryptography.
That said, I'm not sure the documentation linked above is really doing it any favors in terms of helping popularizing it.
How does it compare to the others? I started trying to use Zinc but I get lost in all the vocabulary and literature which assumes you already have a background in it.
There's also a neat shm library by that name. Namespace's getting crowded :)
If anyone wondering, because it took me a few hops to find out:
Z3 is a high-performance theorem prover being developed at Microsoft Research.
oh, something new! I thought Z3 is SAT/SMT solver, they must have added something.
Sometimes you can use SMT for “theorem proving”. It is a rather broad term. I don’t think they added something much different than what they already had.
well a SAT solver is kinda sorta a theorem prover right...?
It is. Look up what SMT stands for.
SMT is SAT+arithmetic, no?
Satisfiability Modulo Theories
Shin Megami Tensei?
Or a BMW, or a groundbreaking electro mechanical computer, depending :)
I was hoping for the mechanical computer...
nailed!
I’m working on a DO-178C compliant verification suite for avionics software with Z3 at work, criminally underrated
