Meta-ticket: SAT and SMT #19000
Description
This ticket collects tickets necessary to strengthen Maxima solve with a state-of-the-art SMT-solver. The interface will be the open SMT-LIB 2.0 and so there is a wide choice of packages of which Z3 certainly is the best at the moment.
- basic assumptions on symbolic functions #18999 - add assumptions on defined/hard-coded functions
-
- SMT-solver benchmark on typical solved and unsolved (by Maxima) problems
-
- SMT-LIB interface
-
- experimental SMT-solver package
Pynac will have access to Sage assumptions with version 0.4.3 but the kind of solver is irrelevant with this.

Solving with SMT solvers rather means proving satisfiablity, in which they are very good. They also can give an example solution.
