Constructor Detail

MeetingProbabilitySet

public MeetingProbabilitySet()

Constructor. Creates a probability set with empty node-probability mapping.

MeetingProbabilitySet

public MeetingProbabilitySet(java.util.List<java.lang.Integer> initiallyKnownNodes)

Constructor. Creates a probability set with equal probability for all the given node indexes.

Method Detail

updateMeetingProbFor

public void updateMeetingProbFor(java.lang.Integer index)

Updates meeting probability for the given node index.

 P(b) = P(b)_old + 1
 Normalize{P}

I.e., The probability of the given node index is increased by one and then all the probabilities are normalized so that their sum equals to 1.

Parameters:

index - The node index to update the probability for

getProbFor

public double getProbFor(java.lang.Integer index)

Returns the current delivery probability value for the given node index

Parameters:

index - The index of the node to look the P for

Returns:

the current delivery probability value

getAllProbs

public java.util.Map<java.lang.Integer,java.lang.Double> getAllProbs()

Returns a reference to the probability map of this probability set

Returns:

a reference to the probability map of this probability set

getLastUpdateTime

public double getLastUpdateTime()

Returns the time when this probability set was last updated

Returns:

the time when this probability set was last updated

replicate

public MeetingProbabilitySet replicate()

Returns a deep copy of the probability set

Returns:

a deep copy of the probability set

toString

public java.lang.String toString()

Returns a String presentation of the probabilities

Overrides:

toString in class java.lang.Object

Returns:

a String presentation of the probabilities
