public class SearchAlgorithm
extends java.lang.Object
implements OptionHandler, java.io.Serializable, RevisionHandler
This is the base class for all search algorithms for learning Bayes networks. It contains some common code, used by other network structure search algorithms, and should not be used by itself.

    * #### listOptions  
    public java.util.Enumeration listOptions()  
    Returns an enumeration describing the available options.  
    Specified by:  
    `[listOptions](../../../../../weka/core/OptionHandler.html#listOptions--)` in interface `[OptionHandler](../../../../../weka/core/OptionHandler.html "interface in weka.core")`  
    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.  
    Specified by:  
    `[setOptions](../../../../../weka/core/OptionHandler.html#setOptions-java.lang.String:A-)` in interface `[OptionHandler](../../../../../weka/core/OptionHandler.html "interface in weka.core")`  
    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](../../../../../weka/core/OptionHandler.html#getOptions--)` in interface `[OptionHandler](../../../../../weka/core/OptionHandler.html "interface in weka.core")`  
    Returns:  
    an array of strings suitable for passing to setOptions  
    * #### toString  
    public java.lang.String toString()  
    a string representation of the algorithm  
    Overrides:  
    `toString` in class `java.lang.Object`  
    Returns:  
    a string representation  
    * #### buildStructure  
    public void buildStructure([BayesNet](../../../../../weka/classifiers/bayes/BayesNet.html "class in weka.classifiers.bayes") bayesNet,  
                               [Instances](../../../../../weka/core/Instances.html "class in weka.core") instances)  
                        throws java.lang.Exception  
    buildStructure determines the network structure/graph of the network. The default behavior is creating a network where all nodes have the first node as its parent (i.e., a BayesNet that behaves like a naive Bayes classifier). This method can be overridden by derived classes to restrict the class of network structures that are acceptable.  
    Parameters:  
    `bayesNet` \- the network  
    `instances` \- the data to use  
    Throws:  
    `java.lang.Exception` \- if something goes wrong  
    * #### maxNrOfParentsTipText  
    public java.lang.String maxNrOfParentsTipText()  
    Returns:  
    a string to describe the MaxNrOfParentsoption.  
    * #### initAsNaiveBayesTipText  
    public java.lang.String initAsNaiveBayesTipText()  
    Returns:  
    a string to describe the InitAsNaiveBayes option.  
    * #### getRevision  
    public java.lang.String getRevision()  
    Returns the revision string.  
    Specified by:  
    `[getRevision](../../../../../weka/core/RevisionHandler.html#getRevision--)` in interface `[RevisionHandler](../../../../../weka/core/RevisionHandler.html "interface in weka.core")`  
    Returns:  
    the revision
