English abstract:
Inprocessing techniques have become one of the most promising advancements in SAT solving over the last decade. Some inprocessing techniques modify a propositional formula in non model-perserving ways. These operations are very problematic when Craig inter- polants must be extracted: existing methods take resolution proofs as an input, but these inferences require stronger proof systems; state-of-the-art solvers generate DRAT proofs. We present the first method to transform DRAT proofs into resolution-like proofs by eliminating satisfiability-preserving RAT inferences. This solves the problem of extracting interpolants from DRAT proofs.
