hi!
With the aid of SPOT I am developing a counter-example guided synthesizer
in python. See [1] if interested for details.
My question is:
I am trying to parse twa_run in python,
namely, parse the labels of the each step (`spot.impl.step`).
Is there a python way to walk through BDD?
(The label is a simple cube expressed in BDD, and I need to convert it into
my internal structure)
(yes, this is rather a question about python interface for buddy)
(no, that is not feature request:) if not possible, I will simply print the
label and parse the string, that is not crucial)
[1]
The idea is
- guess the model,
- then model check it and get a counter-example
- then encode the counter-example into the "guesser" (which uses an SMT
solver)
thanks,
Ayrat
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
