摘　　要：提出了自适应范围DNA(ARDNA)软计算模型框架 ,并着重论述了设计变量统计特性自适应调整策略和自适应范围DNA解码方法及其简化计算公式 .ARDNA克服了传统DNA计算中设计变量编码长度和计算精度之间的矛盾 ,通过有限长的DNA编码实现预定的计算精度 .函数优化应用实例说明ARDNA对设计变量的取值范围无需先验知识 。A framework of an adaptive range deoxyribonucleci acid(ARDNA) soft computing model was proposed.(ARDNA) distributed design candidates according to the normal distribution of design variables in the present population.The adaptive adjusting strategy for statistic characteristics of design variables,and ARDNA decoding method and its approximately (realized) technology were given.ARDNA resolved the contradiction between the length of DNA string and computing precision.Finally,it was applied to minimization of the multi-modal function.The simulation results demonstrate that it doesnot need the prior knowledge for the range of design variables and it has the strong capability of searching globally.
