用L-systems和遗传算法实现的叶子形状建模
Modeling of the Leaf Shapes Using L-systems and Genetic Algorithms
【摘要】 阐述了组合两类技术的一种方法:用L-systems和遗传算法(GA)获取一种改写表达式描述叶子形状。一个L-systems用于构造给定改写表达式,而GA是用于改写表达式的适应参数。介绍了用目标函数实现实值参数替换方法,研究结果表明提出的方法产生可以接受的输 出效果。
【Abstract】 This paper presents a method that combines two techniques: L-systems and genetic algorithms (GA) to search for a rewriting expressio describing leaf shapes. An L-system is used to construct the shape of a given rewriting expression and GA is used to search for the rewriting expression fitting parameters. The replacement of real value parameters with tag-functions is introduced. The result shows that the proposed method produces a acceptable output.
