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. returns Integer is virtual; end FunctionSet;
