Claim 4:
5. The method according to claim 4, wherein the step of optimizing the value of the diffusion factor by using the multi-objective and multi-verse optimization algorithm in the step b is, specifically, to perform optimization in the following steps:
(1) establish a single-variable optimization model, wherein an optimization variable is the diffusion factor p;
(2) initialize the multi-objective and multi-verse optimization algorithm, and set an algorithm parameter;
(3) arrange and archive all universe groups by expansion rate;
(4) screen out an optimal universe from a Pareto solution set as a universal leader;
(5) open a black-white hole tunnel and a wormhole tunnel, wherein objects in universe can pass through the black-white hole tunnel and the wormhole tunnel self-adaptively until a lower expansion rate is acquired; and
(6) determine a search frequency:
if the search frequency reaches a set threshold, output an optimal solution for determining the value of the diffusion factor;
otherwise, add 1 to the search frequency, and repeat the steps (3) to (6) until the search frequency reaches the set threshold.
