It would be nice to actually support CVC4. `--help` says `--smt [path] Path to the SMT solver (usually Z3, but could be any SMT2-compatible solver)`, but the code strongly assumes Z3 (to use CVC4, on…

Hi Daniel,
I keep getting a warning from Kind2 failing in some state invariant generator.
I was curious what happens when you set "--check_sat_assume" to false?
Is the verification still sound? W…

## Motivation
Vampire supports input written in the TPTP- and the SMT-LIB2-syntax. Currently, Vampire interprets its input by default using TPTP, which can be changed to SMT-LIB2 with the option `--i…

Hi,
would it be possible to export the extracted formula in DIMACS format (for further analysis with SAT solvers)?
Right now it seems the SMTLIB format is internally used with Z3. Am I right?

Currently when we compile rational literals to SMTLib we simply cast the `Rational` value back to a `double` and then print the result. Unfortunately this obviously runs into floating point precision …

This assertion seems to protect against users injecting uninterpreted constants from being put in constraints.
The following input triggers this assertion, though without ever inspecting a model.

Hi, for the following formula with ^, z3 return `sat` while cvc5 return `unsat`.
```
(declare-fun var1 () Real)
(assert
(distinct (^ var1 0.0) 1.0))
(check-sat)
```
