I was told that while some denied the possibility of doing this and others were in doubt, there were none who maintained that it was actually possible. On the basis of the above I formulated the following very general problem for myself: Given any configuration of the river and the branches into which it may divide, as well as any number of bridges, determine whether or not it is possible to cross each bridge exactly once.
我被告知，虽然有些人否定这样做的可能性：另有一些小存有疑心，但没有人坚称这么做实际上是可能的。根据以上所述，我向自己提出如下这样-一个很普通的问题:如已知一条河流及其支流形成的流势图，此外还知道河道上有若干座桥，试判定是否可能有一条能通过每座桥的路线，并且每座桥只能通过一次。
