Releases: vale1410/bule
Stable release with some improvements, bug fixes, and a linux binary.
Bule with a Standard Library of Encodings
Bule now provides a standard library with encodings for
- implicit and explicit reachability
- cardinality constraints
- index and log encodings
See folder std_lib.
Furthermore, three modelling examples with benchmark instances for argumentation, positional games and STRIPS planning are added.
Please check doc/tutorial for more information.
Last but not least, attached is also our tool paper for SAT22.
Bule Version 4.0.0
Bule is reimplemented in Ocaml with slight changes to the syntax and new sat of features.
Please check doc/tutorial for more information.
SAT2022 submission.
Improved Speed on Ground Facts in Generators
This should be a small speed improvement over the previous version.
Fix issues with dimacs and unit propagation
Cleanup code and removed unused fragments.
Decided to remove my implementation of unit propagation as it caused more problems and was not needed anymore.
Now there is only a solve and ground command.
with ground -t=0 a dimacs formula for SAT or QBF solvers is generated.
Supporting clause definitions as Implication and improved parsing
Bule support (restricted) implications in a clause definition with straight forward semantics.
dom[1..2].
dom[X] :: p(X) -> dom[Y]: ~q(Y).
grounds to
~p(1) | ~q(1) | ~q(2).
~p(2) | ~q(1) | ~q(2).
.
Left hand side of the implication is separated by & (a conjunction) and right hand (disjunction) with |.
Other structures are not allowed and the parser will complain!
New Bule Syntax using `|`
We have listened to the community of SAT Programmers have adapted syntax accordingly:
Literals in clauses are separated by pipe | and not anymore with comma , .
The order of Iterators (big OR) within clauses is written first facts with commas , and then a colon : and the literal.
F1 , F2 ... F4 : L | etc.
Now everything in Bule is read left to right. Much easier if one comes from normal languages and template engines.
The new use of | eases the visual understand of the clause. This way it is much easier to understand the semantic of a ,.
Have a look at the tests in test-input and a big set of examples. All files are adapted.
We welcome feedback from the community! Bule is still work in progress and you can influence the development.
