关于“七座桥的故事”现在差不多连小学生都已经知道,对于一个图能不能一笔画出, 更是几乎成为“常识”了.但你知道当初欧拉是如何解决七桥问题的吗? 普鲁士的哥尼斯堡镇有一个岛叫奈发夫, 普雷格尔河的两支绕流其旁(如图所示),七座桥横跨这两条支流,问能不能设计一条散步的路线,使得每座桥恰好走过一次.这就是著名的“哥尼斯堡七桥问题”. About “The Story of the Seven Bridges” Almost nowadays, elementary school students all know that it is almost common sense to draw a picture together, but how do you know Euler solved the Seven Bridge problem? Prussia The town of Königsborg has an island called Nifuf and two rivers of the Preger River circumnavigate it (as shown). Seven bridges span the two tributaries and ask if it is possible to devise a walking route , So that every bridge happens to be just one time.This is the famous “Bridge of the Seven Cornersboro.”
