I have no idea if it is relevant, but I wrote a tiny proof assistant for
a hilbert style first order logic the other day.

set hasUnicode to False at the top if your terminal doesn't support
unicode. fun what one can do in a few hundred lines of haskell..
Hi Ganesh,
manipulating predicate formulae was a central part of my PhD research. I
implemented some normalization and standarcization functions in Haskell -
inspired by term rewriting (like normalization to Boolean ring
representation) as well as (as far as I know) novell ideas (standardization
Hi,
That sounds like it might be quite useful. What I'm doing is generating
some predicates that involve addition/subtraction/comparison of integers
and concatenation/comparison of lists of some abstract thing, and then
trying to simplify them. An example would be simplifying

it'd be more convenient, though not insurmountable, if that code was
BSD3-licenced, since it will fit in better with the licence for camp

Hi,
Are there any Haskell libraries around for manipulating predicate
formulae? I had a look on hackage but couldn't spot anything.
I am generating complex expressions that I'd like some programmatic help
in simplifying.
