Forward |
Adapts an objective function with only value implemented
to provide a gradient as well. Gradient calculation is
done using the finite difference method, specifically
forward differences.
For each gradient computed, the algorithm requires an
additional number of function evaluations equal to the
functions's number of input parameters.
