1. The map: the graph G is a two-tuple of an ordered pair of set a of certain elements in a non-empty finite set of V and V,Note: g= (v,a), where V (Vertex) is the set of vertices of graph G, a (ARC) is the arc set of Figure G .2. Correlation

1. What is Data miningData mining is the process of automatically discovering useful information in a large data repository. Data mining techniques are used to probe large databases and discover useful patterns that were previously unknown. Data

Abstract Factory mode is the creation mode of objects, and he is a further extension of the factory method model.Suppose a subsystem requires some product objects, and these products belong to more than one product hierarchy. The abstract factory

To find the longest common substring of n stringsIt's been so long since I wrote Sam.Turn the first string into a suffix automaton and match it with other strings.Each node records the maximum length of each string matched aboveThen the contribution

Title: Probably meaning is given a sequence a[0],a[1]....a[n-1] and an integer k, ask if there is such two subscript Yes Np-sum (i,j) =k, here Np-sum (i,j) =a[i]-a[i+1]+a[i+2]-... + (-1) ^ (j-1) *a[j].Idea: We can maintain the suffix of this

Concept:HDFs blocks a large file (similar to a traditional file system) and stores it on different datanode. However, this block is a logical concept, larger than the default is 64M.Hadoop runs in "manager-worker" mode. Namenode is the manager,
