24 deferred class MultipleVarFunction from math
26 -- Describes the virtual functions associated with a multiple variable function.
33 -- Returns the number of variables of the function
39 Value(me: in out; X: Vector; F: out Real)
40 ---Purpose: Computes the values of the Functions <F> for the
42 -- returns True if the computation was done successfully,
49 GetStateNumber(me: in out)
50 ---Purpose: return the state of the function corresponding to the latestt
51 -- call of any methods associated to the function. This
52 -- function is called by each of the algorithms described
53 -- later which define the function Integer
54 -- Algorithm::StateNumber(). The algorithm has the
55 -- responsibility to call this function when it has found
56 -- a solution (i.e. a root or a minimum) and has to maintain
57 -- the association between the solution found and this
59 -- Byu default, this method returns 0 (which means for the
60 -- algorithm: no state has been saved). It is the
61 -- responsibility of the programmer to decide if he needs
62 -- to save the current state of the function and to return
63 -- an Integer that allows retrieval of the state.
