Question: give n vertices and m edges, and then ask you to calculate that each vertex can only be in one ring (Hamilton ring), and the minimum cost of all vertices is only one time.
Analysis
Graph creation scheme:
Split each vertex into two I and II
Then s connects all I, capacity 1, cost 0
II connect all t,

Maximum Flow with minimum cost
I. Definition and TheoremMinimum fee maximum flow: Set g to s as the source t for the network, C is the capacity of G, B is the unit traffic fee of G, B [I] [J] =-B [I] [J]. If F is a G stream, B (f) = Σ (fij * BIJ ), (I, j) in E (G) and fij> 0. The biggest Flow Problem of the minimum cost is to find the maximum flow f of the Network G and minimize the

Oracle Optimizer: Migrating to using the cost-based optimizer-----series 1.3
3.2.3 Available CBO mode
The CBO has two modes of operation: All_rows and First_rows.
The goal of First_rows is to return rows as quickly as possible. This pattern tells the optimizer that response time is most important. It prefers nested join methods. First_rows also deals with rows with cost as the prim

purchased in 2005 and 2006, running the WinXP standard, the memory is about 256M to 1G. If this part of the PC to upgrade to Vista, the need to pay not only the software costs of Vista, but also to pay some of the hardware upgrade costs. The retail price of Vista is also quite high. Because these "master" PCs have been unable to run Vista, need to upgrade in memory support and graphics. If you do so, you may also encounter compatibility issues that are not desirable.

Issue background:Huffman tree is widely used in coding. Here, we only care about the construction of the Huffman tree.Given the number of columns {pi}={p0, p1, ..., pn-1}, the process of constructing the Huffman tree with this number is as follows:1. Find the minimum of two in the {pi}, set to PA and Pb, remove the PA and Pb from the {pi}, and add them to the {pi}In The cost of this process is recorded as PA + PB.2. Repeat step 1 until only one number
