All Implemented Interfaces:

Serializable, Cloneable, Meriting, Initializable, PropertySupplying

public class RandomizeGroupMerit
extends AbstractNightMerit
implements Initializable

This merit keeps all targets within a group at the same number of nightly observations. If this target is amongst the ones with the highest number of picks, it returns a randomized value, otherwise 1. A group is all observable targets (or all observable include group targets), diminished by the exclude group.

Method Detail

init

public void init()

Specified by:

init in interface Initializable

getMerit

public double getMerit(GlobalGrouping set,
                       Appointable target,
                       Collection<Appointable> allothers,
                       long within)

Description copied from interface: Meriting

Calculates the maximal merit for a special target within the stated amount of time. Non-time dependandt merits may readily ignore the time-span parameter. The provided list of targets should give all relevant targets, i.e. for subsets only the daughters. If the set of parameters is not sufficient for calculating a merit, zero should be returned.

Specified by:

getMerit in interface Meriting

Parameters:

set - Current observing conditions.

target - The actual target.

allothers - All targets, observable or not.

within - The relevant time span in ms.

getRank

private int getRank(HistoryAware target,
                    GlobalGrouping set)

Returns the number of relevant picks in this night.

Parameters:

target -

set -
