|
|
|
|
## 0.6.1
|
|
|
|
- add simple functor for DOT backend
|
|
- various bugfixes
|
|
|
|
## 0.6
|
|
|
|
### Feature
|
|
|
|
- An already instantiated sat solver in the Sat module
|
|
- A `full_slice` function for running possibly expensive satisfiability
|
|
tests (in SMT) when a propositional model has been found
|
|
- Forgetful propagations: propagations whose reason (i.e clause) is not watched
|
|
|
|
## 0.5.1
|
|
|
|
### Bug
|
|
|
|
- Removed some needless allocations
|
|
|
|
### Breaking
|
|
|
|
- Better interface for mcsat propagations
|
|
|
|
### Feature
|
|
|
|
- Allow level 0 semantic propagations
|
|
|
|
## 0.5
|
|
|
|
### Bug
|
|
|
|
- Grow heap when adding local hyps
|
|
- Avoid forgetting some one atom clauses
|
|
- Fixed a bug for propagations at level 0
|
|
- Late propagations need to be re-propagated
|
|
- Fixed conflict at level 0
|
|
- Avoid forgetting some theory conflict clauses
|
|
|
|
### Breaking
|
|
|
|
- Changed `if_sat` interface
|
|
|
|
## 0.4.1
|
|

|
### Bug
|
|
|
|

|
|
|
|
## 0.4
|
|
|
|
- performance improvements
|
|
- many bugfixes
|
|
- more tests
|
|
|
|
### Breaking
|
|
|
|
- remove push/pop (source of many bugs)
|
|
- replaced by solve : assumptions:lit list -> unit -> result
|
|
|
|
### Features
|
|
|
|
- Accept late conflict clauses
|
|
- cleaner API, moving some types outside the client-required interface
|
|
|
|
## 0.3
|
|
|
|
### Features
|
|
|
|
- Proofs for atoms at level 0
|
|
- Compatibility with ocaml >= 4.00
|
|
- Released some restrictions on dummy sat theories
|
|
|
|
## 0.2
|
|
|
|
### Breaking
|
|
|
|
- Log argument has been removed from functors
|
|
- All the functors now take a dummy last argument to ensure the solver modules are unique
|
|
|
|
### Features
|
|
|
|
- push/pop operations
|
|
- access to decision level when evaluating literals
|
