          Args:
              parameter_space (dict): dictionary containing
                  parameter/list-of-values pairs.
              result_parsing_function (function): user-defined function, taking a
                  result dictionary as argument, that can be used to parse the
                  result files and return a list of values.
              runs (int): number of runs to gather for each parameter
                  combination.
