public class RandomMerit
extends AbstractMerit

A merit calculating a random gain between zero and KEY_IMPACT. Used to ad a random element to scheduling to avoid a too strongly pronounced window function.

Constructor Detail

RandomMerit

public RandomMerit(Map prop)

Constructs a new random merit, defaulting the KEY_IMPACT. Proper creation should be done using the AbstractMerit.createMerit(java.util.Map) method. This create method also takes care of proper parameter overloading.

Method Detail

getMerit

public double getMerit(ParameterClustering set,
                       TargetDefinition target,
                       Collection ignore,
                       long dummy)

Calculates the actual gain using a random value between zero and KEY_IMPACT.

Parameters:

set - Current observing conditions.

target - The actual target.

ignore - The list of targetes relevant to the actual target.

dummy - The relevant time span in ms.
