Constructor Detail

RandomMerit

public RandomMerit(Map<String,String> prop)

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

Method Detail

getMerit

public double getMerit(GlobalGrouping set,
                       Appointable target,
                       Collection<Appointable> 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 - All targets, observable or not.

dummy - The relevant time span in ms.
