已知n个城市之间的相互距离，现有一个推销员必须遍访这n个城市，并且每个城市只能访问一次，最后又必须返回出发城市。如何安排他对这些城市的访问次序，可使其旅行路线的总长度最短？ (Known n city between the distance, the existing of a salesman to be visited this n city, and each city can only be visited once, finally to return to the starting city. How to arrange for him to visit the city order, which can make the total length of the shortest travel route)

这本 stevenkay 关于谱估计 信号估计 部分的英文书。 要想搞透信号估计，检测，，还是要看看这个的。 这个领域工作的人，若需要讨论，也可以找我。 毕竟能够和你讨论的人，非常少。希望我能帮上一点点。(This stevenkay on spectrum estimation signal estimation part of the English books. To estimate things through signals, detection, or to see that' s. People who work in this area, if necessary to discuss, you can find me. After all, who can discuss with you, very small. Hope I can be a little bit.)
