WebGiven a graph with N vertices. Check whether an undirected graph is a tree or not. An undirected graph is tree if it has following properties. There is no cycle. The graph is connected. Another way to understand this is to say that a tree is an undirected graph in which any two vertices are connected by exactly one path. WebFrequent graph mining has been proposed to find interesting patterns (i.e., frequent sub-graphs) from databases composed of graph transaction data, which can effectively express complex and large data in the real world. In addition, various applications for graph mining have been suggested. Traditional graph pattern mining methods use a single minimum …
