| 摘 要： | 通过对DNA计算的研究,提出了一种在DNA计算的基础上引入一种基于Lokta-Volterra方程的生态竞争繁殖、家庭选择机制等的求解多模态函数的进化算法,使得群体能够保持多样性,并有效地避免了早熟收敛,通过对测试函数的求解,同时搜索到多模函数多个极值峰点,取得了令人满意的结果。

| Abstract: | As a new method of computing,DNA computing makes use of DNA moleculare to compute.DNA computing has attracted great interest for its incomparable advantage to conventional computation.A kind of evolutionary algorithms based on the basic DNA computing is put forward in the paper.Furthermore,several new operators such as competitive reproduce based on a kind of transformative Lokta-Volterra equation and family selection mechanism are introduced in the algorithm.The algorithm can keep the population's diversity well and avoid premature convergence.The simulated results are much better than the ones given by GAs and have proved the validity of the algorithm. |
