Dinic's general idea is similar to the EK (in fact, a lot of the general idea of the algorithm is the same), but dinic in each search for augmented road first BFS a bit, to each point plus a grade, and rules: Only the level of two adjacent points can go, So when it comes to DFS, you lose a lot of useless, unnecessary roads.1#include 2#include 3#include 4#include 5#include 6 using namespacestd;7 Const intinf=1000000000, maxn=100000+Ten, maxm=1000000+Ten;8 intTo[maxm],nex[maxm],
Do you know the DOS command parameters? For example, the dos dir command parameters, using dir/p will display a screen of directory information after the pause. These parameters are also called switches. Parameters or switches to users with a lot of flexibility, can adapt to a variety of different needs! Like software, hardware has parameters and switches can be set, hardware settings switch is called "jumper" (Jumper). Proficient in mastering jumper is one of the necessary technology of the mac
, we can see that because there are n people, the minimum cost of the dead multi-source Multi-sink point is the maximum flow. But in fact, the question has already given a prompt, followed by a matrix of k N * M, in fact, we want to calculate the minimum cost of each kind of goods first, then sum. Through analysis, it is easy to find that the minimum cost of the goods in k is good and does not affect each other.3. How to Create a graph?The number of the Source Vertex s and the sink vertex t is d

pass is still there is not full stream edge can go some traffic. The idea of this kind of augmented path algorithm is to constantly find the "augmented path" on the "Residue Network", and then modify the traffic on the remaining network until it does not pass.

ArrayFeatures of the array in the Go language:The length of the array is fixed, and the length is part of the array typeis a value type that, when assigned or passed as a parameter, copies the entire array, not the pointerTo define the syntax for an array:var arr1 = [5]int{1,2} // [5]int{1, 2, 0, 0, 0} 未初始化的值,就默认初始化为该类型的默认值var arr2 = [...]int{1,2,3} // [3]int{1,2,3} 长度可由初始化的元素个数确定var arr3 = [5]int{1: 20, 4: 50} // 可使用索引来初始化,其他值仍然是对应类型的默认值var arr4 = [2][3]int{{1,2,3}, {2,3,4}} /
capacity of the slice, and after the slice slice is created, the storage space for 10 elements is reserved. Run the above example to understand:650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/5A/12/wKioL1T1pQPSLsJfAABYae7tmek339.jpg "title=" Make slice. png "alt=" wkiol1t1pqpslsjfaabyae7tmek339.jpg "/>From the results, the number of slices slice elements is 3, and the element default padding is 0, because the slice slice capacity is 10, so you can also append 7 elements to the slice.
source array, the other is defined by the Make function, essentially the same, is in memory through the initialization of the array of memory, divided into several small blocks to store the array elements, Slice then refers to the entire or local array element.Direct initialization of a slice:
Copy Code code as follows:
s: = []int{1, 2, 3}
Note that this is a little bit different from initializing the array, some students think this is a definition and initialization of

A network flow with upper and lower bounds is limited to the flow of the edge and must be within the range of [down,up] [down,up].
In fact, the normal network flow is a special network flow with the upper and lower bounds, but the traffic limit for each edge is [0,cap] [0,cap]. category
There are two types of network flows with upper and lower bounds:
