Module Fun_sat.Make

A functional SAT solver implementation.

Parameters

module _ : Theory.S

Signature

type t
exception Sat of t
exception Unsat of Explanation.t
exception I_dont_know of t
val empty : ?selector:(Expr.t -> bool) -> unit -> t
val declare : t -> Id.typed -> t
val push : t -> int -> t
val pop : t -> int -> t

pop env n pops n assertion levels of the environment env.

  • raises Errors.Error

    if there is no n assertion levels in env.
