If decision list fails to classify the current instance, a new rule according to this current instance is generated and added to the decision list.<br/> <br/> The option -V switches on voting, which means that at the end of the generation all instances are reclassified to the class value that is supported by the most rules.<br/> <br/> This data generator can generate 'boolean' attributes (= nominal with the values {true, false}) and numeric attributes. The rules can be 'A' or 'NOT A' for boolean values and 'B < random_value' or 'B >= random_value' for numeric values. <p/> <!-- globalinfo-end --> <!-- options-start --> Valid options are: <p/> <pre>
