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 Spot Team!
First of all, thanks for providing and maintaining such a great tool!
I stumbled over a problem with formulas in polish notation: Parsing a formula like “-> a b” returns the “syntax error, unexpected implication operator” (Also tested on the website). It seems like implication and equivalence are not supported by that parser. Is there a technical reason for that and if not, could you give me a hint how to implement it?
Thanks in advance
Niklas Metzger
