This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
A symbolic model checker for Dynamic Epistemic Logic.
You can find a complete literate Haskell documentation in the file SMCDEL.pdf.

You can try SMCDEL online here: https://w4eg.de/malvin/illc/smcdelweb/
On Debian, just do
sudo apt install graphviz dot2tex.
- Use stack from https://www.stackage.org
stack buildwill compile everything. This might fail if one of the BDD packages written in C and C++ is missing. In this case, install those manually and then try
stack installwill put two executables
smcdel-webinto ~/.local/bin which should be in your
Create a text file which describes the knowledge structure and the formulas you want to check for truth or validity:
-- Three Muddy Children in SMCDEL VARS 1,2,3 LAW Top OBS alice: 2,3 bob: 1,3 carol: 1,2 WHERE? [ ! (1|2|3) ] alices knows whether 1 VALID? [ ! (1|2|3) ] [ ! ((~ (alice knows whether 1)) & (~ (bob knows whether 2)) & (~ (carol knows whether 3))) ] [ ! ((~ (alice knows whether 1)) & (~ (bob knows whether 2)) & (~ (carol knows whether 3))) ] (alice,bob,carol) comknow that (1 & 2 & 3)
Run “smcdel textfile” resulting in:
>> smcdel MuddyShort.smcdel.txt SMCDEL 1.0 by Malvin Gattinger -- https://github.com/jrclogic/SMCDEL At which states is ... true?   Is ... valid on the given structure? True
More example files are in the folder Examples.
To deal with more complex models and formulas, use SMCDEL as a Haskell module.
Examples can be found in

Used BDD packages
SMCDEL can be used with different BDD packages. To compile and run the benchmarks you will have to install all of them.
SMCDEL.Other.NonS5 implements general knowledge structures. They are
equivalent to Kripke models which are not based on equivalence relations.
