VMware virtual machines in use, as software and data increase, the virtual disk occupies a larger amount of hard disk space, but after the data is deleted, it does not automatically reduce the physical hard disk space occupiedInstead, it continues

In the summary of the principle of apriori algorithm, we summarize the principle of apriori algorithm. As an algorithm for mining frequent itemsets, the Apriori algorithm needs to scan the data multiple times, and I/O is a big bottleneck. In order

Dijkstra Application Range:The weights of each edge in the graph are not negative.The shortest path is widely used in the real world, such as finding the shortest path on a map, and this algorithm is very important.The algorithm idea is simple, it
