针对遗传算法中的两项重要技术——编码问题和适应度函数的设计做了深入探讨,利用遗传算法全局最优的特点,对教学设备进行了评标,同时对适应度函数的设计针对以往的设计方法提出新的见解,对其设计方案提出改进,引入AHP算法进行适应度函数的设计,给出利用AHP算法进行适应度函数设计的全过程。 Aiming at the design of two important technologies - coding problem and fitness function in genetic algorithm, this paper makes a deep research on the design of fitness function and makes use of the global optimization of genetic algorithm to evaluate the teaching equipment. At the same time, This paper puts forward some new ideas, puts forward some improvements to its design scheme, introduces AHP algorithm to design fitness function, and gives the whole process of using AHP algorithm to design fitness function.
