Abstract: To solve function optimization problem,we have described ant colony algorithm adding binary coding of genetic algorithm and developed pheromone update strategy.In the experiment,we have used a new structure of searching matrix.Because the matrix’s dimension decreases,the performance of algorithm improves considerably.The improved algorithm has been tested for variety of different classical test functions.And the algorithm can handle these optimization problems very wel1.

摘要: 为了求解一般的函数优化,在对标准蚁群算法研究的基础上,将遗传算法的编码方式引入蚁群算法,对蚁群算法的信息素更新进行改进,并提出一种搜索矩阵表达方式,减少了搜索矩阵的规模,从而提高了搜索效率。通过对几个经典测试函数的求解,证明了算法的有效性。
