The free-theorems-seq package

[Tags:library, public-domain]

Given a term, this program calculates a set of "optimal" free theorems that hold in a lambda calculus with selective strictness. It omits totality (in general, bottom-reflection) and other restrictions when possible. The underlying theory is described in the paper "Taming Selective Strictness" (ATPS'09) by Daniel Seidel and Janis Voigtländer. A webinterface for the program is running online at http://www-ps.iai.uni-bonn.de/cgi-bin/polyseq.cgi or available offline via the package http://hackage.haskell.org/package/free-theorems-seq-webui.

Related to this package you may be interested in the online free theorem generator at http://www-ps.iai.uni-bonn.de/ft that is also available offline via http://hackage.haskell.org/package/free-theorems-webui. Additionally interesting may be the counterexample generator for free theorems that exemplifies the need of strictness conditions imposed by general recursion. It can be downloaded at http://hackage.haskell.org/package/free-theorems-counterexamples or used via a webinterface at http://www-ps.iai.uni-bonn.de/cgi-bin/exfind.cgi.

Readme for free-theorems-seq

Readme for free-theorems-seq-1.0

The module free-theorems-seq-0.1 can be installed via

cabal install

or the following way:

runhaskell Setup.hs configure --user
runhaskell Setup.hs build
runhaskell Setup.hs haddock
runhaskell Setup.hs install

runhaskell Setup.hs haddock builds the documentation.
This step is not necessary.

After installation the modules
        Language.Haskell.FreeTheorems.Variations.PolySeq.PolySeq
        Language.Haskell.FreeTheorems.Variations.PolySeq.PrettyPrint
        Language.Haskell.FreeTheorems.Variations.PolySeq.TypeTranslator
        Language.Haskell.FreeTheorems.Variations.PolySeq.TheoremGen
        Language.Haskell.FreeTheorems.Variations.PolySeq.Parser.ParseTerm
        Language.Haskell.FreeTheorems.Variations.PolySeq.Highlight
are available.

The functionality of the library is also available via a webinterface
that is either available via the package at

http://hackage.haskell.org/package/free-theorems-seq-webui

or can be used online at

http://www-ps.iai.uni-bonn.de/cgi-bin/polyseq.cgi.

Enjoy.
