摘　　要：简要介绍了遗传算法的基本原理和特点,接着将遗传算法与传统优化算法作了比较,然后介绍了遗传算法在实际应用中的改进方法和在工程结构优化中的应用现状,并用一个三杆桁架的算例来说明遗传算法的优越性,最后提出遗传算法存在的主要问题和总结展望。The basic principle and features of genetic algorithms are briefly introduced and then the comparision between the genetic algorithm and the traditional optimization one is made. In consequence, the actual application of the genetic algorithm to the engineering structure optimization is also introduced as well as its improvement. The advantages of genetic algorithm are expatiated by using a computation example about 3-pole truss. Finally, existing problems on genetic algorithm are suggested, together with its prospect in use concluded.
