Abstract
A major computational task in implementing the Differential Semblancce Optimization method (see the companion paper [2] for a presentation of the method) is an accurate computation of the gradient of the objective function. In this paper , we show how such a computation may be accomplished, and assess its accuracy on a representative example.
