From http://blog.csdn.net/shuangde800 Question Source: Click to open the link Question (From lrj Training Guide) Mobile Phone Positioning in the cellular network is a basic problem. Assume that the cell network has learned that the mobile phone is in C1, C2 ,..., One of the regions of CN is the easiest way to search for mobile phones in these regions at the same time. However, this is a waste of bandwidth. Because the probability of the mob

that von Neumann proposes (one-dimensional world). Rules such as:There are two kinds of states: off and on. Its survival depends on its adjacent two cell states.According to the rules, the above eight possibilities can be obtained.The rule can be self-prepared, each state corresponds to two possible, so there is a total of 2^8 256 different rules can be discussed. Numbers are numbered using 2, which results in a 0-255 system that is numbered for different rules (not duplicates).If you traverse

Analysis:A state is a set of ordered collections that do not intersect and are set to all regions. It is obvious that enumerating the elements of a collection is not bearable,Write the desired formula, you will find a greedy, when the size of each set is determined, the probability of a large priority access is optimal. It's easy to prove and intuitive.So first you sort from big to small. The definition state F[i][j] represents the minimum expectation of the group I, starting with J.Transfer is

Ultraviolet A 1386-Cellular Automaton Question Link Given an N-lattice ring, there is a distance d. Each change adds the lattice within the distance d to the ring. The result is mod m. After K transformations, numbers on the ring Idea: the matrix is very good. Each Location corresponds to one location and the remaining location is 0, but this matrix has a size of 500, which is a little big. It is not suitable to directly calculate the matrix through N

This backup and restore topic is associated with all SQL Server databases. A differential backup is based on the most recent full data backup. A differential backup captures only data that has changed since the full backup. The full backup on which the differential backup is based is called the "baseline" of the variance. Full backups (except replication backups only) can be used as a benchmark for a serie

Myth #30:30 Misconceptions about Backup It's all wrong. Before starting a misunderstanding about backup, if you don't know the basics of backup, see my previous article in TechNet Magazine: Understanding SQL Server Backups . 30-01) Backup operation can cause blocking No, the backup does not cause a lock on the user object, although the burden of the backup on the IO system causes it to appear blocked, but not in practice. The only special case is t

What are backup retention policies (retention policy)A retention policy refers to whether a backup is to be retained and how long it is retained. You can use the Configure retention policy command to create a consistent, automated backup retention policy. When a backup policy is in effect, Rman considers the backup of the data files and control files to be obsolete, meaning that these backups are no longer needed for recovery based on user configurati

backup file for this test should be put together with other regular backups for recovery purposes. That is, if you perform a regular differential backup after testing the backup file, these differential backups will be backed up as the starting point for the restore with this test. Assuming that the size of all the database files is equal, the smallest measure you get is the maximum backup throughput

Article Title: linux automatically deletes backups n days ago. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Linux is a system that automatically generates files, such as logs, emails, and backups. Although hard disks are cheap now, we can have a lot of hard disk space
