Public Member Functions

 SqrtXX (const std::string &s, const Gecode::FloatVal &d, Gecode::FloatNum st)
 Create and register test.
virtual MaybeType solution (const Assignment &x) const
 Test whether x is solution
virtual void post (Gecode::Space &home, Gecode::FloatVarArray &x)
 Post constraint on x.
 Test (const std::string &s, int a, const Gecode::FloatVal &d, Gecode::FloatNum st, AssignmentType at, bool r)
 Constructor.
 Test (const std::string &s, int a, Gecode::FloatNum min, Gecode::FloatNum max, Gecode::FloatNum st, AssignmentType at, bool r)
 Constructor.
virtual Assignmentassignment (void) const
 Create assignment.
virtual bool extendAssignement (Assignment &a) const
 Complete the current assignment to get a feasible one (which satisfies all constraint). If such an assignment is computed, it returns true, false otherwise.
bool subsumed (const TestSpace &ts) const
 Test if ts is subsumed or not (i.e. if there is no more propagator unless the assignment is an extended assigment.
virtual bool ignore (const Assignment &a) const
 Whether to ignore assignment for reification.
virtual void post (Gecode::Space &home, Gecode::FloatVarArray &x, Gecode::Reify r)
 Post reified constraint.
virtual bool run (void)
 Perform test.
bool flip (void)
 Flip a coin and return true or false randomly.
