module Formula : Solver_intf.FORMULAformulas
val push_level : t -> unitCreate a new backtrack level
val pop_levels : t -> int -> unitPop n levels of the theory
val partial_check :
t ->
(Solver_intf.void, Formula.t, Solver_intf.void, proof) Solver_intf.acts ->
unitAssume the formulas in the slice, possibly using the slice to push new formulas to be propagated or to raising a conflict or to add new lemmas.
val final_check :
t ->
(Solver_intf.void, Formula.t, Solver_intf.void, proof) Solver_intf.acts ->
unitCalled at the end of the search in case a model has been found. If no new clause is pushed, then proof search ends and "sat" is returned; if lemmas are added, search is resumed; if a conflict clause is added, search backtracks and then resumes.
