Artifact for the Paper "Fast Verified SCCs for Probabilistic Model Checking"

The artifact that backs up the data in our ATVA 2023 Paper titled "Fast Verified SCCs for Probabilistic Model Checking". This artifact contains the proof files for Isabelle/HOL. Running the proofs yields a LLVM implementation of Gabow's algorithm that can be compiled to a dynamic library. This artifact also contains a version of the Modest toolset that can use this library to replace the built-in SCC algorithm. Lastly, the artifact contains scripts that reproduce the results in the paper. The additional reference contains a link to browsable version of the artifact that allows proofs to be inspected without downloading anything.
