getVersion

public java.lang.String getVersion()

Description copied from interface: Algorithm

may return the version of the Algorithm.

Specified by:

getVersion in interface Algorithm

Overrides:

getVersion in class AbstractAlgorithm

calculate

public double calculate(double[] params)

Description copied from interface: Algorithm

calculates the result of the Algorithm for these parameters. Calling the Algorithm multiple times with the same params has to be consistent

Specified by:

calculate in interface Algorithm

Parameters:

params - the Array has to have as many elements as specified with Algorithm.getNrParams()

Returns:

the result
