smartnet coverage

First, greedy algorithm introductionThe basic idea of the algorithm: from one of the initial solution of the problem to proceed step by step, according to an optimization measure, each step must ensure that the local optimal solution can be obtained. Each step considers only one data, and his selection should satisfy the conditions of local optimization. If the next data and part of the optimal solution are no longer feasible, the data is not added to the partial solution until all the data is e

Personal experience: Two-point map what is not known, the Internet for reference, please refer to http://blog.csdn.net/thundermrbird/article/details/52231639With their own understanding, the dichotomy is to split the graph into two halves, the two sides of the point through the boundary link. Matching means that there are no two edges that have the same vertex, that is, one vertex is connected to at most one edge.The Hungarian algorithm is to use the augmented road to update, carefully think so,

Google Maps adds practical new features: A real-time view of global forest coverage Even now, the global forest area is still shrinking, in order to make people more aware of this grim situation, Google recently launched a new interactive map-"Global forest Monitoring (Forest Watch)", which can show real-time global forest coverage. There will be a number of sources for the map, including data on NASA's fo

Minimum function Dependency Set I. Equivalence and coverage Definition: The two dependency set F and G on the relational pattern r 　　 Second, minimum function dependency set Definition: If the function dependency set F satisfies the following conditions, it is said that f is the minimum function dependency set or minimum overwrite. The right part of any of the functions in ①f has only one property; There is no such function dependent x→a in ②f, which

Poj 2376 greedy range coverage Question: Select as few intervals as possible for n intervals to cover 1 ~ T this interval If output-1 cannot be overwritten Ideas: Classic greedy interval coverage Sort all intervals from small to large to take the interval at the rightmost of the end point.

in a chessboard of 2kx2k squares, a square is different from other squares, calling it a special square and calling it a special chessboard. problem: Use 4 different forms of L-shaped dominoes to cover all squares except special squares on a given special chessboard, and any 2 must not overlap. There are 4k cases where special squares appear on the board. Thus, for any k>=0, there are 4k different special chessboard. It is easy to know that in any 2k * 2k chessboard, the number of L-type dominoe

A taxi company has M appointments, and each reservation occupies one line: (for example) a B c d (a, B) indicates the starting point of the reservation. (c, d) indicates the end of the task. The previous time is the start time, and the end time of the task is | a-c | + | B-d | + start time, so for the M booking, how many vehicles can be dispatched at least? Analysis: At first, I thought of the Time Scheduling Problem in the greedy algorithm, but later I found an error. Here we should use the min

POJ 3020 Antenna Placement (bipartite graph creation training + minimum path coverage) Antenna Placement Time Limit:1000 MS Memory Limit:65536 K Total Submissions:6692 Accepted:3325 DescriptionThe Global Aerial Research Centre has been allotted the task of building the maximum th generation of mobile phone nets in Sweden. the most striking reason why they got the job, is their discovery of a new, highly noise

Problem description: In a checkerboard consisting of 2 k × 2 k squares, a square is different from other squares. It is called a special square and a special checkerboard. In the Board coverage problem, we need to use four different types of L-shaped bone cards in the figure to cover all squares except the special square on the given special board, And no two L-type dominoes can overlap. Analysis: When k> 0, the 2 k × 2 k board is divided into 4 2
