Question: Give an undirected graph, as well as the start and end points. To delete some edges so that the start point and the end point are not connected, the number of edges to be deleted should be as few as possible when the sum of the right values of the deleted edges is the smallest. Obtain a ratio: the number of remaining edges and the number of deleted edges.
Idea: the minimum
, then the sum is: V [J1] * W [J1] + .. + V [JK] * W [JK] Please help Jin Ming design a shopping order meeting the requirements.

The script for implementing the function was quickly written, but Google did not find a simple way to add custom buttons to the resource manager for a long time. I mistakenly thought it was okay, but it was a custom button added to IE.
The successful result of subfolder is to study a uuid. Download and use jug.
In fact, you only need to press the folder option twice. Or you can use shortcuts to Incr
Linux ([? la?n?ks or L?n?ks]) kernel developer Greg Kroah-hartmant, speaking in Berlin, said that Linux has become the world's largest software development project.The latest Linux 4.5 kernel contains more than 21 million lines of code, but not all devices run these 21 million lines of code, Kroah-hartman for example, his computer runs about 1.6 million lines of code, and the phone runs 2.5 million lines. The core code accounts for about 5% of the total code, 35% of which are network-related cod
Microsoft supports the "Virtual XP Mode" in Windows 7 of the next operating system, and the XP model meets the requirements of Windows 7 users running the software in a virtual XP environment. However, if a user wishes to use the service successfully, it is necessary to determine whether their machine hardware configuration meets the requirements, in particular the need to determine whether the CPU used by the machine itself supports virtualization technology. Intel's official website confirms t
, the only MacBook in the market is equipped with only one interface, this design is inevitably questioned. However, this usb-c interface actually represents future computer connectivity standards that support the USB 3.1 specification with a transmission rate of up to 10gbit/seconds, with rich connectivity. Only through this interface, you can complete the charging, data transmission, image output and so on. Of course, the inconvenience in using the place is the need to pass a compatible access
