| virtual Standard_Integer | NbVariables () const override |
| | returns the number of variables of the energy.
|

| virtual Standard_Boolean | Value (const math_Vector &X, Standard_Real &E) override |
| | computes the values of the Energys E for the variable <X>. Returns True if the computation was done successfully, False otherwise.
|
| |
| virtual Standard_Boolean | Gradient (const math_Vector &X, math_Vector &G) override |
| | computes the gradient <G> of the energys for the variable <X>. Returns True if the computation was done successfully, False otherwise.
|
| |
| virtual Standard_Boolean | Values (const math_Vector &X, Standard_Real &E, math_Vector &G) override |
| | computes the Energy <E> and the gradient <G> of the energy for the variable <X>. Returns True if the computation was done successfully, False otherwise.
|
| |
| virtual Standard_Boolean | Values (const math_Vector &X, Standard_Real &E, math_Vector &G, math_Matrix &H) override |
| | computes the Energy <E>, the gradient <G> and the Hessian <H> of the energy for the variable <X>. Returns True if the computation was done successfully, False otherwise.
|
| |
| virtual Standard_Boolean | Variable (math_Vector &X) const |
| | compute the variables <X> which correspond with the field <MyPoles>

| const Handle< TColgp_HArray1OfPnt2d > & | Poles () const |
| | return the poles
|
| |
| virtual Standard_Integer | GetStateNumber () |
| | return the state of the function corresponding to the latestt call of any methods associated to the function. This function is called by each of the algorithms described later which define 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.
