This topic can be done with the minimum cost and the maximum flow. In order to review the optimal matching of the bipartite graph, we wrote a KM program.
At first, because I had not processed the double KM before, I was going to multiply the decimal number by a certain power of 10 into an integer, but I found that WA was always there, and then I simply wrote it using double, and then the AC.

(Villagers who have the money to buy a house but not necessarily can buy it depends on what the village leader assigns).Input data contains multiple sets of test cases, the first row of each set of data input n, indicating the number of houses (also the number of people home), followed by n rows, the number of n per row represents the price of the room of the second village name (nOutput make the maximum revenue value for each set of data, one row for each set of outputs.Sample
A tough question
First, the input is very painful. According to the online experts, the question matrix is reversed. Then I gave it back.
If it is a match between n and n, there is no pressure to directly obtain the negative value of KM.
However, if the points on both sides are different, it is said that there will be problems.

why calculate Setup time of the Slack need to consider adding cycles, Hold Time when you don't need it? Summary one:Because the data delay,launch edge and capture edge do not correspond to the same clock edge of the clock signal source clocks, due to the existence of the time of Setup, the addition cycle needs to be considered. When a single clock cycle is checked, the tool defaults to capture Edge-launch edge=1 cycles.Hold time because the two corre

It is worth mentioning that if we use the KM algorithm to find the perfect matching of minimum weights, we need to initialize the edge weight to the MAX-G [I] [j] and then find the perfect matching of the maximum right, and then convert the result back.
If you initialize G [I] [j] to-G [I] [j] to find the perfect matching of the maximum permission, the program I write Will time out, at the moment, I have no idea whether this idea is a problem or my writing is a problem.

First, we need to convert the characters in the string into the number of [0, k-1] with the same meaning, and then scan the array sequentially, we can get the maximum value of various matching between the two sets of numbers, this completes the graph creation.
Then use the KM algorithm to find the optimal match.

We can split a fish into two points, which respectively represent attack and attack, and then set the Edge Weight of G [I] [j] = 1 to value [I].^ Value [j], and then use the KM algorithm to find the optimal matching of the Bipartite Graph.

Each augmentation requires an O (n) sub-index change. Each time you change the top, enumerate the edges to find the D value, the complexity is O (N2), and the total complexity is O (N4). S
distance s. When 1 times slack is made on each side, the branches that start from S and have a maximum level of 1 are generated. That is, the shortest path to the vertices with a maximum of 1 edges associated with S is found, and the 2nd-pass relaxation of each edge creates a 2nd-level branch, which means that the shortest path of those vertices connected by 2 edges is found .... Because the shortest path contains up to |v|-1 edges only, you only nee
Hipchat functions like campfire, Sazneo, and other online collaborative tools, and is similar to Yammer and Salesforce's corporate social platforms. You can build your own chat rooms for individual projects or groups, and you can easily initiate one-on-one chats. The IM system also integrates team file management and sharing, dragging and dragging to complete the save operation.

Sourcetree after installation need to use account login to authorize, previously can not login, but now is forced to login.
Although it is free license, but encounter force majeure factors, landing is not very convenient, here record skip this initialization step.
After installation, go to the Sourcetree directory under User's local folder, no new

When installing confluence, the Confluence application and database is not on a server, the company moved the office during the last period of time, resulting in a change in the server IP, so that confluence will not start up, you need to modify the confluence connection to the database address, In fact, it is very simple to modify the address, mainly to find the Confluence connection database configuration file.
The first step is to find the Confluence installation directory, my installation
