FYI: I am running Bosphorus from the docker container built on the latest commit that you so kindly made after my previous bug report: https://github.com/meelgroup/bosphorus/commit/dd9654af6e380a77e9ff8dfe4ec72b6da90edb40
Ah, you have a bug in your ANF. I will think about how to warn about this. Your line is:
x(372) x(27) + x(373) x(23) + x(374) x(20) + x(28) x(30) + x(15) + x(375) x(28) + x(20) + x(21) + x(23) + x(24) + x(25) + x(28) + x(29) + x(31) + x(376) x(19) + x(377) x(374) + x(378) x(379) + x(375) x(30) + x(380) x(22) + x(376) x(381) + x(379) x(14) + x(382) x(22) + x(377) x(20) + x(372) x(383) + x(384) x(385) + x(382) x(380) + x(386) x(23) + x(373) x(386) + x(378) x(14) + x(24) x(384) + x(27) x(383) + x(381) x(19) + x(24) x(385)x(34) + x(3) + x(1)
Spot the error :D The issue is x(24) * x(385)x(34)
, you are missing a *
between the two x
-s. I'll try to catch this kind of thing next time :)

Oh! I'm sorry, I should've caught that. I was thrown off by the error. It successfully worked when I limited the output. Programming is tricky sometimes.

Hi!
Thanks again for making this tool avaiable. I've been having a lot of fun playing around with it. It works great normally, but I've hit a (hopefully interesting) snag.
You mention in the README.md that:
I seem to have found an instance where I get a PBoriError at 510 variables, with as many clauses. I have been able to successfully run bosphorus on ANF's with many more variables, so this seems like an issue worth reporting. The full output I'm getting is as follows:
Please find the .anf in the attachment (renamed to .txt, because github does not allow uploads otherwise) polybori_error.txt
For context, this is an ANF of the first 32-bit Mersenne Twister state transform on the seed bits (x(0)..x(31), with a myriad of help-variables sprinkled in. I'm not 100% sure yet whether it is an actual representation of the mersenne twister, but in any case it should be a valid ANF
I hope you will be able to look at this! If you need any further information, please do let me know.
Best,
Erwin
