Constructor Detail

SimpleProductSemantics

public SimpleProductSemantics(double epsilon,
                              double precision)

Creates a new simple product semantics with the given epsilon parameter for the simple vote aggregation function.

Parameters:

epsilon - some non-negative value

precision - precision of comparisons between values.

SimpleProductSemantics

public SimpleProductSemantics(double epsilon)

Creates a new simple product semantics with the given epsilon parameter for the simple vote aggregation function. The value 0.001 is used as precision of comparisons between values.

Parameters:

epsilon - some non-negative value

bottomElement in class AbstractSocialSemantics<java.lang.Double>

Returns:

the bottom element of this semantics.

topElement

public java.lang.Double topElement()

Description copied from class: AbstractSocialSemantics

Returns the top element of this semantics.

Specified by:

topElement in class AbstractSocialSemantics<java.lang.Double>

Returns:
