摘 要: 研究参加长江竞渡的游泳者对游泳方向的最优选择问题。在游泳者速度大小不变的前提下,针对2002年比赛期间的水流分布给出了新颖的游泳者竞渡策略以及有趣的最佳游泳路线。对水流速度为一般连续分布的情形,采用多段折线逼近法,给出通用的模型及其求解步骤,并论证了该方法在实际应用中的可操作性。 The optimization of swimming direction in the contest of crossing the Yangtze river is studied. Under the condition that a swimmer has the same speed in size, a new strategy is given and a novel swimming route for the swimmer to win in 2002 is shown. For the general case that the velocity of river is continuous, a normal method to deduce the optimization of swimming direction by fold lines is discussed.
