ISRES.gradient_num_diff¶
- static ISRES.gradient_num_diff(x_center, f, epsilon, max_evals_grouped=1)¶
We compute the gradient with the numeric differentiation in the parallel way, around the point x_center.
- Parameters
x_center (ndarray) – point around which we compute the gradient
f (func) – the function of which the gradient is to be computed.
epsilon (float) – the epsilon used in the numeric differentiation.
max_evals_grouped (int) – max evals grouped
- Returns
the gradient computed
- Return type
