The number of candidate samples per iteration, formula_6, is not determined a priori and can vary in a wide range. Smaller values, for example formula_105, lead to more local search behavior. Larger values, for example formula_106 with default value formula_107, render the search more global. Sometimes the algorithm is repeatedly restarted with increasing formula_6 by a factor of two for each restart. Besides of setting formula_6 (or possibly formula_99 instead, if for example formula_6 is predetermined by the number of available processors), the above introduced parameters are not specific to the given objective function and therefore not meant to be modified by the user.
