For ease of deployment, the picosat source (namely picosat.c and picosat.h) is included in this project. A program that solves SAT problems is called a SAT solver. Modern SAT solvers often utilize conflict-driven clause learning (CDCL) [5][15]. A SAT solver assigns 0 or 1 to variables by making decisions, as a mean of satisfiability reasoning. Activity-based decision heuristic is a robust strategy widely used in modern SAT solvers [6][2][3]. A The easiest way to install it, along with a Z3 binary, is to use Python's package manager pip.

For the SAT solver, the meaning of the variables is insignificant since the solution does not depend on it, and the solver operates only with the indices of the variables. However, the correspondence between the variable index and its meaning in the definition of the FSM is necessary for the automatic creation of all the conditions and …This short tutorial serves as an introduction to using Z3 through its Python interface as well as learning how to encode general problems into SAT problems.
