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

Throws:

java.lang.Exception
