Inputs

(For outputs, see below)

alternatives

Description:

Alternatives to consider.

preferences

Description:

Aggregated preferences matrix.

  • Tag: alternativesMatrix

preference information

Description:

Preference information about alternatives. Strength for the alternative is given to the value of true, weakness for false, when no value is given, the alternative does not gain strength or weakness.

parameters

Description:

Parameter specifies the algorithm to calculate ranking. There are three algorithms to choose from: PageRank, HITS and Salsa.

GUI information:

  • Parameter values can be defined via the GUI or the XMCDA file, by default via GUI.

  • Name: algorithm type

    • Type: drop-down list
    • Possible values:
      • PrefRank with preference information I (XMCDA label : prefrank_with_preference_information_1) (default)
      • PrefRank with preference information II (XMCDA label : prefrank_with_preference_information_2)
      • PrefRank with preference information III (XMCDA label : prefrank_with_preference_information_3)
  • Name: damping factor

    Damping factor

    • Constraint description: The real value must be between 0 and 1
    • Type: float
    • Default value: 0.15
  • Name: number of iteration

    Number of iteration

    • Constraint description: The value should be greater than 1
    • Type: integer
    • Default value: 100
  • Name: Run averaging if not converge?

    Turning on the version with averaging the score value, if after “number of iteration” iteration the score does not converge, that is: the maximum score difference between the last two iterations is greater than 0.001.

    • Default value: false
  • Name: Earlier stop if converge?

    Earlier stop if the maximum difference in score between two consecutive iterations is less than 0.00001

    • Default value: true
