virtual Standard_Boolean Value (const Standard_Real X, Standard_Real &F)=0
 Computes the value of the function <F> for a given value of
variable <X>.
returns True if the computation was done successfully,
False otherwise.

virtual Standard_Integer GetStateNumber ()
 returns the state of the function corresponding to the
latest call of any methods associated with the function.
This function is called by each of the algorithms
described later which defined the function Integer
Algorithm::StateNumber(). The algorithm has the
responsibility to call this function when it has found
a solution (i.e. a root or a minimum) and has to maintain
the association between the solution found and this
StateNumber.
Byu default, this method returns 0 (which means for the
algorithm: no state has been saved). It is the
responsibility of the programmer to decide if he needs
to save the current state of the function and to return
an Integer that allows retrieval of the state.
