obdd-0.8.2: obdd.cabal
Name: obdd
Version: 0.8.2
Cabal-Version: >= 1.8
Build-type: Simple
Synopsis: Ordered Reduced Binary Decision Diagrams
Description:
Construct, combine and query OBDDs;
an efficient representation for formulas in propositional logic.
.
This is mostly educational.
The BDDs do not share nodes (there is no persistent BDD base) and this might introduce inefficiencies.
.
An important (for me, in teaching) feature is
that I can immediately draw the BDD to an X11 window (via graphviz).
For example, to show the effect of different variable orderings,
try this in ghci (type 'q' to close the drawing windows).
.
> import Prelude hiding (not,(&&),(||),and,or,any,all)
> import OBDD
> let f [] = false; f (x:y:zs) = x && y || f zs
> display $ f $ map variable [1,2,3,4,5,6]
> display $ f $ map variable [1,4,2,5,3,6]
.
'OBDD' implements 'Ersatz.Boolean' which re-defines
Boolean operations from the Prelude. The recommended way of using this
is shown in the previous example.
.
If you want better performance, use a library with a persistent BDD base,
e.g., <http://vlsi.colorado.edu/%7Efabio/CUDD/ CUDD>
<https://hackage.haskell.org/package/cudd Haskell bindings>,
see <https://gitlab.imn.htwk-leipzig.de/waldmann/min-comp-sort this example>.
