【摘要】 2008年全国大学生数学建模竞赛C题是关于汶川大地震的地面搜索问题.为寻找用时最短的搜索路径,主要从缩短不搜索时的行进路线考虑,建立了"S式"折线模型和螺线模型,并对模型结果进行理论验证,其中螺线模型的方法构思巧妙,结果合理且较优.更多还原

【Abstract】 The question C in 2008 National Undergraduate Mathematical Contest in Modeling is about the Wenchuan Earthquake ground searching problem.To find the search path with the shortest time,mainly consider to shorten the route of non-searching,establish "S-style" broken line model and spiral model,and verify the models theoretically: spiral model is ingenious and its result is reasonable and better.更多还原
