Abstract: Fitness is the driving force of Darwinian natural selection and of both conventional genetic algorithms and genetic programming ,based on which to evaluate individuals of current population and to reproduce the next generation from the current generation.In Modeling of Genetic Programming,based on traditional Fitness Function,Fitness Function is improved and adjusted by means of ways for this design. In the end,through the experiment, it is found that improved fitness function improves the performance of accuracy in pest forecasting.
Key words: Genetic Programming Fitness Function Code Explosion
摘要: 适应性函数是遗传算法和遗传程序设计得以实现的关键因素,是评价个体好坏的定量表述,决定着演化过程中群体选择复制及群体整体性的质量。本文在GP程序过程中在常见适应性函数的基础上加其以优化和调整,最后通过实例验证了优化调整后的适应性函数在病虫害预测预报中的准确度有了一定的提高。
