Note
	You can find an example of feature algorithms in the training catalog ($CADENAS/training/training.cip) at \v11_news\value_ranges\value_ranges_with_condition\din_1771.prj.

So-called characteristic algorithms are used to express dependencies between variables . In the following example figure, you can see that the variable NENN is represented by the variables H, B and L .

NENN = '$H.x$B.x$L.'
