@ -33,6 +33,12 @@ New in spot 0.8.3a:
- A new direct simulation reduction has been implemented. It
works directly on TGBAs. It is in src/tgbaalgos/simlation.hh,
and it can be tested via ltl2tgba's -RDS option.
- unabbreviate_wm() is a function that rewrite the W and M operators
of LTL formulae using R and U. This is called whenever we output
a formula in Spin syntax. By combining this with the aforementioned
PSL rewriting rules, many PSL formulae that use simple SERE can be
converted into LTL formulae that can be feed to tools that only
understand U and R. The web interface will let you do this.
- changes to the on-line translator:
+ SVG output is available
+ can display some properties of a formula
