SAT-Based Parallel Planning Using a Split Representation of Actions
Planning based on propositional SAT(isfiability) is a powerful approach to computing step-optimal plans given a parallel execution semantics. In this setting: (i) a solution plan ...

Fast Set Bounds Propagation Using a BDD-SAT Hybrid
Binary Decision Diagram (BDD) based set bounds propagation is a powerful approach to solving set-constraint satisfaction problems. However, prior BDD based techniques incur the si...

SAT sweeping with local observability don't-cares
SAT sweeping is a method for simplifying an AND/INVERTER graph (AIG) by systematically merging graph vertices from the inputs towards the outputs using a combination of structural...

Beaver: Engineering an Efficient SMT Solver for Bit-Vector Arithmetic
We present the key ideas in the design and implementation of Beaver, an SMT solver for quantifier-free finite-precision bit-vector logic (QF BV). Beaver uses an eager approach, enc...
