摘　　要：打洞函数法是一类有效的确定性全局优化方法,通过打洞函数可以评估不同的粒度空间.利用全局优化方法构造粒化算法,并在改进打洞函数的概念后给出了一个易操作的单参数打洞函数及粒化算法,数值实验表明所给粒化算法是有效的.A new idea to model global optimization by using granule calculation was put forward. It was based on mathematical theory of tunneling function method which was one of the effective deterministic methods. Such tunneling function method was viewed as a new computing architecture that focused on processing information granules. A more practicable one-parameter tunneling function was proposed. A novel algorithm was presented with satisfactory numerical results.
