[Haskell-cafe] Predicate logic (FOL) reasoning in Haskell

I was recently passed this reference, which I thought was worthy of sharing here... I've not yet read it myself in detail, but at a glance it looks very readable. http://staff.science.uva.nl/~bcate/core/rwt.pdf [[ Reasoning with Tableaux Jan van Eijck CWI and ILLC, Amsterdam, Uil-OTS, Utrecht ... The paper contains the full Haskell [5] code of a free variable tableau theorem prover for predicate logic, written in `literate programming' style. ]] #g ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
