“梯度投影法”是近年来苏联铁路路线优化设计中正在推荐采用的方法,本文着重从数学原理上介绍了这个方法,阐述了使用这个方法应当注意的问题,并给出了计算粗框图,为编制我国铁路路线优化设计的电算程序奠定了基础。
“Gradient projection method” is the method that is recommended in the optimization design of the Soviet railway line in recent years. This paper introduces the method from the mathematical principle, expounds the problems that should be noticed when using this method, The compilation of the computer program for optimizing the design of railway routes in China laid the foundation.
