infinite Itemsets, the learning of the real variable function is very clear, it is meaningless to say an algorithm alone.Second, Quorom algorithmQuorom algorithm is commonly used in distributed systems to ensure data redundancy and eventual consistency of the voting algorithm, the main mathematical ideas derived from the pigeon nest principle.In distributed storage systems with redundant data, redundant data Objects store multiple copies between different machines. But at the same time multiple

Microsoft has invested heavily in developing augmented reality technology (AR). According to the latest news from the foreign media, Microsoft HoloLens, an inventor recently said that the smartphone has died, the future will
In distributed system, redundant data is the means of guaranteeing reliability, so the consistency maintenance of redundant data is very important. In general, a write operation must update all redundant data to be called a successful end. For example, a data on 5 devices have redundancy, because do not know the reading data will fall on which device, then a write operation, must be 5 devices are updated to complete, write operations to return.For systems with frequent write operations, the bott
