### TAN

    public TAN()

Method Detail

### buildStructure

    public void buildStructure(BayesNet bayesNet,
                               Instances instances)
                        throws java.lang.Exception

  buildStructure determines the network structure/graph of the network using the maximimum weight spanning tree algorithm of Chow and Liu

  Overrides:
    `buildStructure` in class `SearchAlgorithm`
  Throws:
    `java.lang.Exception`

### listOptions

    public java.util.Enumeration listOptions()

  Returns an enumeration describing the available options.

  Specified by:
    `listOptions` in interface `OptionHandler`
  Overrides:
    `listOptions` in class `GlobalScoreSearchAlgorithm`
  Returns:
    an enumeration of all the available options.

### setOptions

    public void setOptions(java.lang.String[] options)
                    throws java.lang.Exception

  Parses a given list of options. Valid options are:

  Specified by:
    `setOptions` in interface `OptionHandler`
  Overrides:
    `setOptions` in class `GlobalScoreSearchAlgorithm`
  Parameters:
    `options` - the list of options as an array of strings
  Throws:
    `java.lang.Exception` - if an option is not supported

### getOptions

    public java.lang.String[] getOptions()

  Gets the current settings of the Classifier.

  Specified by:
    `getOptions` in interface `OptionHandler`
  Overrides:
    `getOptions` in class `GlobalScoreSearchAlgorithm`
  Returns:
    an array of strings suitable for passing to setOptions

### globalInfo

    public java.lang.String globalInfo()

  This will return a string describing the classifier.

  Overrides:
    `globalInfo` in class `GlobalScoreSearchAlgorithm`
  Returns:
    The string.
