摘要
动态规划是运筹学的一个重要分支 ,学生只有同时掌握动态规划的逆序解法和顺序解法 ,才能全面理解和掌握动态规划理论 ,才有可能将动态规划模型熟练应用于实际问题之中。由于动态规划模型比较抽象 ,教材只对动态规划的逆序解法做了重点介绍 ,而对顺序解法重视不够 ,不利于学生全面理解和掌握动态规划理论。笔者在教学实践中摸索出的“对比”教学方法 ,能够帮助学生深刻理解动态规划理论 ,获得了较好的教学效果。
Dynamic programming is an important branch of the operational research, and only when the students have simultaneously grasped both the inverse and sequential solutions, can they understand the theory of dynamic programming thoroughly and skillfully put into execution the module of dynamic programming. However, as the module of dynamic programming sounds too abstract, the textbooks usually give scrupulous explanations to the inverse solutions instead of the sequential ones, which hinders the students from a good understanding of the theory of dynamic programming. The article offers a probe into the author's teaching of the theory of dynamic programming, and sums up the “method of comparison and contrast”, which proves to be effective in helping the students in their study of this subject.
