Application of OFN Numbers in the Artificial Duroc Pigs Optimization (ADPO) Method

In the article, the authors propose a new optimization method inspired directly by the behavior of the Duroc pig herd, which was bred in New England. The new metaheuristics called Artificial Duroc Pigs Optimization (ADPO) is an example of the successful implementation of Ordered Fuzzy Numbers into a swarm optimization method. The notation of OFN is suitable for describing the behavior of the pig herd in the article. The experiments were carried out for eight benchmark functions with many extremes. For comparison, experiments with PSO, BA and GA methods were carried out on the same functions. In most tests, the results obtained by ADPO were the best.
