Re: [isabelle] [isabelle-dev] Circular reasoning via multithreading seems too easy
Absolute certainty cannot be obtained by millions of lines of code
(prover, compiler, OS, ...) running on real hardware, but, as Hugo
points out, independent checking goes some ways toward improved
Truly independent checking is asking a lot of a reader of a formal
development, but Coq has stand-alone
coqchk; some HOLs can be checked by HOL-zero.
What is the story for stand-alone checking of Isabelle/Hol developments?
