| Abstract: | The piecewise model of "Crossing Yangtze River" is a solution model of problem D in the National College Mathematical Modeling Competition of 2003. This paper discusses the optimal solution of the model when the swimmers adjust their swimming direction piecewise. It is supposed under the condition that the speed of the water changes linearly and the swimmers keep their speed of swimming constantly in crossing Yangtze River. |
