In general,given two vertices V and W in a graph,it is not always possible to find a path connecting them;such a path will exist only when the graph is 'in one piece'.

D8 |一般而言，给定图的两个顶点V和W并非总能找到连接它们的路；只有当图是"在一块中"时，这样的路才存在。

Comment: A graph is CONNECTED if there is a path connecting every two vertices.

说明：如果任意两个顶点之间都存在路径相连，那么称这个图为"连接图"

In Graph Theory,we shall also be interested in connected graphs in which there is only one path connecting each pair of vertices;such graphs are called trees（generalizing the idea of a family tree）.

在图论中，人们还对树感兴趣，树是每一对顶点间只有一条路的连通图。

All the conspicuity maps will be integrated into a single conspicuity map which will be used to extract interesting map by nonlinear relaxation algorithm. The top-down attention mechanism uses the knowledge of visual task and object.
