Hi all,
I am using SPOT by following command
autfilt --equivalent-to=A.hoa B.hoa
to check the equivalence of two Buchi automata A.hoa and B.hoa (attached).
It returns nothing and it means two automata are not equivalent.
But actually I used GOAL and RABIT to check the equivalence, they said yes.
I think you may want to have a look.
Regards,
Yong
Hi Yong,
Thank you for the report. It seems that this bug, which I can reproduce with Spot 2.4.4, was fixed in Spot 2.5.
The bug disappears after commit bd739a5712, a major rewrite of the determinization algorithm.
Best regards,
