 +===== General case =====
 +
 +In general case when we have two networks **N**<sub>a</sub> = (**A**,**L**<sub>a</sub>) and  **N**<sub>b</sub> = (**B**,**L**<sub>b</sub>) we have to transform them to the common set of vertices **V**=**A**∪**B** and apply the operations afterward.
 +
 +This can be done in different ways:
 +  * by switching off the option ''Read - Save vertices labels'' in the ''Options'' menu. In this case the vertex //i// gets the label ''v''//i//.
 +  * if all vertices in **A** have different labels and also all vertices in **B** have different labels then we can use the option ''Networks / Match Vertex Labels'' ...
