The main idea: give a table, each table points to one of the four squares around, ask you can change some of the lattice points, ask all the squares in the circle minimum need to change how much.Idea: All the squares are in the circle, because each lattice can only have one out side, so make sure that all the squares have one edge. Create a model of the cost flow, where all points to the meeting point are connected to the flow 1 of the cost 0 of the edge, indicating that you want to accept an in

There are M supply points for goods. It provides k types of goods and N stores. These N stores need to order a certain amount of these k types of goods from the goods points, each supply point has different supply for these k types of goods, and each store has different requirements for k types of goods. Each supply point has different costs for delivering a single item of different types of goods to each store, the relationship between supply points, stores, k types of goods, and costs is now g

Poj 3680 maximum fee stream of Intervals Question: To give n an open range (ai, bi) and the corresponding weight wi, We need to select some ranges. We need to ensure that either of them cannot be overwritten by more than k ranges, and the goal is to maximize the total weight. Analysis: Convert to the maximum charge flow, and change the template of the minimum charge flow. Code: //poj 3680//sep9#include #include #include #include

POJ 3680 Intervals (minimum fee Stream) Question: n intervals. Each interval has a value. You can select several intervals so that no vertex is overwritten for more than k times. Train of Thought: We can discretization the range endpoint and run the expense stream, no more than k times, we can set this corresponding traffic attribute. It is easy to think that the interval endpoint is used as the node, and the cost of connecting a traffic is-a [I]. the

, traditionally in order to overcome relational database defects, improve performance, is to increase the level of memcache to static Web pages, and in SNS, changes too fast, Memchache is powerless to do so, it is necessary to use a new data structure storage to replace the relational database. The other characteristic of the relational database is that it has a fixed table structure, so its extensibility is very poor, and in SNS, the upgrading of the system, the increase of the function, often
