use cases are probably quite limited. We use that to generate
benchmarks for our generic emptiness check procedure.
- ltlsynt --algo=lar uses the new version of to_parity() mentionned
below. The old version is available via --algo=lar.old
Library:
- Historically, Spot only supports LTL with infinite semantics
