解决堵车问题人类该向蜜蜂学习?

　　British scientists have discovered that bees learn to fly the shortest possible route between flowers even if they discover the flowers in a different order.

　　英国科学家发现，尽管花的分布位置不同，蜜蜂总是能够在所有飞行路径中找到最短的那条。

　　The bees are the first animals found to solve "travelling salesman problems".

　　迄今为止，蜜蜂是唯一能够解决“旅行销售者问题”的动物。

　　The travelling salesman must find the shortest route that allows him to visit all locations on his route. Computers solve it by comparing the length of all possible routes and choosing the shortest. However, bees solve it without computer assistance using a brain the size of grass seed.

　　销售员在拜访多个地点的时候要寻求一条最短的路径。计算机将所有可能路径进行比较以后，然后选择一条最短路径。蜜蜂的大脑只有草籽一般大，也没有电脑的帮助，但是却已经找到解决的方法。

　　Nigel Raine, from the School of Biological Sciences at Royal Holloway explains: "Foraging bees solve travelling salesman problems every day. They visit flowers at multiple locations and, because bees use lots of energy to fly, they find a route which keeps flying to a minimum."

　　英国皇家霍洛韦生物科学学院研究人员奈杰尔 雷恩说：“蜜蜂每天都在花丛中飞来飞去，为了采蜜进行飞行是一件很耗精力的事情，所以它们要将飞行控制在最短的距离。因此实际上蜜蜂每天都在解决“旅行销售员问题”。
