    Description copied from class: SearchAlgorithm
    
    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.
    
    Overrides:
    
    buildStructure in class SearchAlgorithm
    
    Parameters:
    
    bayesNet -
    
    instances - the instances to work with
    
    Throws:
    
    java.lang.Exception - if something goes wrong
  - getRevision
```
public java.lang.String getRevision()
```
    Returns the revision string.
    
    Specified by:
    
    getRevision in interface RevisionHandler
    
    Overrides:
    
    getRevision in class SearchAlgorithm
    
    Returns:
    
    the revision
