针对原有的多种群蚁群算法收敛速度慢,运行时间长,容易早熟等缺陷,提出了一种新型异类多种群蚁群算法。算法由多类不同特性蚁群构成,不同蚁群具有不同特质,且优势互补,彼此间具有潜在的合作性。不同种类蚁群搜索时,通过子蚁群间的相似度,自适应选择最互补的蚁群进行信息交换,以加强不同种类蚁群间的协作,增强解的多样性,增强跳出局部最优的能力。TSP仿真结果表明,该算法在搜索速度以及搜索质量方面都有明显的提高。
針對原有的多種群蟻群算法收斂速度慢,運行時間長,容易早熟等缺陷,提齣瞭一種新型異類多種群蟻群算法。算法由多類不同特性蟻群構成,不同蟻群具有不同特質,且優勢互補,彼此間具有潛在的閤作性。不同種類蟻群搜索時,通過子蟻群間的相似度,自適應選擇最互補的蟻群進行信息交換,以加彊不同種類蟻群間的協作,增彊解的多樣性,增彊跳齣跼部最優的能力。TSP倣真結果錶明,該算法在搜索速度以及搜索質量方麵都有明顯的提高。

To overcome the problems of searching speed, running time, and earlier premature of traditional multiple ant colonies algorithm, an improved algorithm is proposed. This algorithm introduces more than one type of ant colonies with different pheromone updating mechanisms. These different types of ant colonies have different searching traits. They can cooperate smoothly each other. Every ant colony adaptively chooses suitable information exchangeable object from more than one potential selected ant colonies, determines the best pheromone exchanging strategy from a variety of options through similarity coefficient among every ant colonies. By this way, the balance between the diversity and convergence of every ant colony is kept desirable. A series of TSP experiments show that this algorithm can generate solutions with better quality and faster speed.
