摘　　要：为解决《机械优化设计》课程教学中算法演示的难题,提出了优化算法动态可视化演示的思想。以单形替换法为对象,介绍了单形替换法的算法原理。提出了将单纯形三个顶点坐标值作为可视化演示关键特征变量的处理方法。在此基础上,分析了单形替换法的动态可视化技术原理,包括算法实现、迭代过程存储与演示动画生成等内容。运用VB开发了单形替换法动态可视化教学软件,通过实例演示证明,该软件有助于学习者更清晰的看到算法的求解过程,有效地提高了教学质量。To solve the teaching problem of algorithm demo in the course of mechanical optimization design,the idea of dynamically and visually showing algorithm was proposed.Taken the simplex replacement method as the research object,the algorithm theory of the method was presented.The processing method of taking the coordinate values of three vertexes of the simplex as the key feature variables was put forward.Based on this,the principle of dynamic visualization technology of the method was analyzed,including the algorithm realization,iteration process storage,demo animation generation,etc.The teaching software of dynamic visualization of simplex replacement method was developed by VB.Through the example demo,it is shown that the software can help the learners to more clearly see the solving process of algorithm.It can effectively improve the teaching quality.
