In particular, the second part proposes a way to tailor benchmarks according to the depths to which programs have to be investigated in order to find all errors. This gives benchmark designers a method to challenge contributors that try to perform well by excessive guessing.enBenchmark generationVerification competitionsError witnessesTemporal logicLTL synthesisBüchi automataModal contractsParallel decompositionModel checkingBisimulation checking004TextBenchmarkRichtigkeit von ErgebnissenFehlermeldungTemporale LogikLogiksyntheseBüchi-AutomatModallogikDekompositionModel CheckingBisimulation
