Concrete methods
The mathematical function that represents the gradient of the objective function represented by objFunction. An approximation using the Differential class is provided as the default implementation of this method, but it is highly encouraged to override this method with a hard-coded implementation of the correct gradient function in order to greatly improve the accuracy of the results.

The function described in this method implementation should correspond to the gradient of the function described in objFunction or else the results obtained in any tests or benchmarks will be void of meaning.
