Pinaka: Symbolic Execution meets Incremental Solving (Competition Contribution)

Abstract

Many modern-day solvers offer functionality for incremental SAT solving, which preserves the state of the solver across invocations. This is beneficial when multiple, closely related SAT queries need to be fed to the solver. Pinaka is a symbolic execution engine which makes aggressive use of incremental SAT solving coupled with eager state infeasibility checks. It is built on top of the CProver/Symex framework. Pinaka supports both Breadth First Search and Depth First Search as state exploration strategies along with partial and full incremental modes. For SVCOMP 2019, Pinaka is configured to use partial incremental mode with Depth First Search strategy.
