Modifier and Type | Method and Description |
---|---|
java.lang.Double |
eval(java.util.Collection<java.lang.Double> vals)
Generalizes this norm on sets of input parameters
(as t-norms are associative, the order is not important).
|
abstract java.lang.Double |
eval(java.lang.Double val1,
java.lang.Double val2)
Evaluates the function for the given elements.
|
Term |
evalTerm(java.util.Collection<Term> vals)
Gives a representation of this norm as a mathematical term.
|
abstract Term |
evalTerm(Term val1,
Term val2)
Gives a representation of this norm as a mathematical term
|
abstract TCoNorm |
getDualCoNorm()
Returns the dual T-conorm of this T-norm.
|
abstract boolean |
isNilpotent()
A T-norm is nilpotent if there are x,y>0 with t(x,y)=0
