  2. The main research work of dissertation can be concluded as follows : 1. two kinds of hybrid strategies of genetic algorithms and tabu search are discussed systematically in this paper. the idea of tabu search is introduced to improve crossover operator and mutation operator of genetic algorithms for the first strategy, while tabu search is executed to a certain proportional selected individuals in the population after genetic evolution of every generation for the second strategy

    本文的主要研究成果概括如下: 1 .論文比較系統地探討了遺傳演算法和禁忌搜索演算法的兩種混合策略:第一種是利用禁忌搜索的思想來改進遺傳演算法的交叉運算元和變異運算元;第二種是對每代中交叉變異后得到的新種群中的一定比例的個體進行禁忌搜索處理。
  3. Research and application of genetic expression programming algorithm based on uniform - design a new evolutionary algorithm named uniformdesign genetic expression programming ugep based on uniformdesign was proposed, which improved the way of generating initial population and also improved hybrid crossover operators. theoretic analysis proves.

    提出了一種基於均勻設計的基因表達式編程演算法ugep ，該演算法對經典的gep演算法做了以下改進：利用混合水平均勻表的構造對初始種群的產生進行改進，保證了解分佈的均勻性引入自適應多親雜交運算元，用均勻優化代替隨機進化。
