All Implemented Interfaces:

CleanUpHandler, Destroyable, GlobalInfoSupporter, LoggingLevelHandler, LoggingSupporter, OptionHandler, Randomizable, SizeOfHandler, Serializable, Comparable

public class RandomOptimiser
extends AbstractOptimiser
implements Randomizable

Generate random parameter values.

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

-iterations <int> (property: iterations)
    The number of iterations to use.
    default: 1000
 

-seed <long> (property: seed)
    The seed value for the random number generator.
    default: 1
