public class RankSearch extends ASSearch implements OptionHandler, TechnicalInformationHandler
-A <attribute evaluator> class name of attribute evaluator to use for ranking. Place any evaluator options LAST on the command line following a "--". eg.: -A weka.attributeSelection.GainRatioAttributeEval ... -- -M (default: weka.attributeSelection.GainRatioAttributeEval)
-S <step size> number of attributes to be added from the ranking in each iteration (default = 1).
-R <start point> point in the ranking to start evaluating from. (default = 0, ie. the head of the ranking).
Options specific to evaluator weka.attributeSelection.GainRatioAttributeEval:
-M treat missing values as a seperate value.
