SMT script generated by Ultimate LassoRanker [1]
Ultimate LassoRanker is a tool that synthesizes ranking functions for
linear lasso programs and implements the techniques presented in [2] and [3].
For generating these SMT scripts Ultimate LassoRanker was used as a sub
procedure of the termination analyzer Ultimate BuchiAutomizer [4] which
implements the techniques presented in [5].
This SMT script belongs to a set of SMT scripts that was generated by applying
revision 11505 of BuchiAutomizer to
- the benchmarks from the demonstration category on termination of the SV-COMP
2014 [6] available at [7],
- the benchmarks from [8] which are available at [9] and,
- benchmarks from the repository of Ultimate LassoRanker.
This set of SMT scripts contains only SMT scripts that we considered to be
difficult because LassoRanker run into a timeout after 10 seconds.
