Check controls

Description

This function checks the input controls.

Usage

check_controls(controls)

Arguments

controls

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.

Value

The checked and filled list controls.
