The first data set encodes a network with 2 nodes, power station 0 with Pmax (0) =15 and Consumer 1 with Cmax (1) =20, and 2 p Ower Transport lines with Lmax (0,1) =20 and Lmax (1,0) =10. The maximum value of Con is 15. The second data set encodes the network from Figure 1.PS: Pit My A problem, ah, the topic looked for a long time to understand, so many data directly scare me, input time

Section Fifth-cloning The object model in PHP5 invokes an object by reference, but sometimes you might want to create a copy of an object and expect the original object to change without affecting the copy. For this purpose, PHP defines a special method called __clone. Like __construct and __destruct, there are two underscores in front. By default, the __clone method creates an object that has the same properties and methods as the original object. If you want to change the default content durin

extranet and the intranet, or it can be a plug-in built into the firewall. When Fw/nat discovers that the external network call signaling is SIP, it forwards it to the ALG (Application layer Gateway) and establishes the communication connection between the intranet pseudo-address terminal and the external network terminal via ALG. After NAT conversion, the via,contact,ower/creator,connection information in the extranet SIP packet needs to be changed

at the same time . QUOTE (X) Returns the value of the parameter that is appropriate for inserting other SQL statements. The string is added as a single quotation mark, and the escape symbol is added before the inner quotation marks. blobs are encoded as hexadecimal text. The current vacuum is implemented using this function. This function is also useful when using triggers to implement undo /Redo functionality. Random () Returns a random number within a
