Either NULL or a named list with the following elements. Missing elements are set to the default values in parentheses.

init_runs (5): The number of initial searches.
init_min (-1): The minimum argument value for the random initialization.
init_max (1): The maximum argument value for the random initialization.
init_iterlim (20): The number of iterations for the initial searches.
neighborhoods (5): The number of nested neighborhoods.
neighbors (5): The number of neighbors in each neighborhood.
beta (0.05): A non-negative weight factor to account for the function's curvature in the selection of the neighbors. If beta = 0, the curvature is ignored. The higher the value, the higher the probability of selecting a neighbor in the direction of the highest function curvature.
iterlim (1000): The maximum number of iterations to be performed before the local search is terminated.
tolerance (1e-6): A positive scalar giving the tolerance for comparing different optimal arguments for equality.
time_limit (NULL): The time limit in seconds for the algorithm.
