交互式遗传算法(IGA)通过人机交互以用户对个体的评估代替传统的适应度函数,在艺术设计等偏向于人类主观感受的领域具有很高的应用价值和广泛的现实意义。文中针对IGA中人的疲劳问题,提出了将根据配对个体之间的相似度值自适应地确定交叉率的方法引入IGA。通过这种方法,可以提高遗传寻优计算的效率,加快IGA的收敛速度,有效缓解用户疲劳。将该方法应用于建筑造型的创新设计中,证明该方法的巨大潜力。
Interactive genetic algorithms (IGA) is an adaptive design for replacing traditional genetic algorithm by means of interaction and clients'individual evaluation. It has high reputation and is of great significance of application.To the problem of human fatigue in IGA,a new kind of genetic algorithm swith adaptive crossover rate based on individuals' similarity is introduced to IGA. In such a way, IGA can get a faster convergence velocity,and the problem of tiredness for users can effectively be solved. The application of this idea in construction creative design shows the great potentiality.
