Public Member Functions

• DecisionEngineMBTF (TheoryCore *core, SearchImplBase *se)
• virtual ~DecisionEngineMBTF ()
• virtual Expr findSplitter (const Expr &e)

  Finds a splitter inside a non const expression. The expression passed in must not be a boolean constant, otherwise a DebugAssert will occur.
  

• virtual void goalSatisfied ()

  Search should call this when it derives 'false'.
  

Protected Member Functions

• virtual bool isBetter (const Expr &e1, const Expr &e2)
