In the network, regardless of the distance between the vertex and the line connects to the line any time. We may write a job network, job network, multiple forms, such as in the following example: .
The network irrespective of the distance between the vertices. And the line is any line. We may write network network has several. Like the following example:
In the network will regardless of the distance between the peak. And the weld line is the line any. We may write network network one several ways such as the following examples .
