computeFactors

protected void computeFactors()

Calculate the factors necessary to transform the linear coordinate into a multidimensional one (which is the the state for each possible node - target and evidence). FactorForNode[i + 1] = ProductOf(NumberOfStates[i]), for all previous nodes (i).

getLinearCoord

protected final int getLinearCoord(int[] multidimensionalCoord)

Get the linear coordinate from the multidimensional one. LinearCoord = SumOf(StateOf[i] * FactorOf[i]), for all possible nodes (i).

Parameters:

multidimensionalCoord - Multidimensional coordinate (represented by the state for each node).

Returns:

The corresponding linear coordinate.

getEvidenceLinearCoord

protected final int getEvidenceLinearCoord(int[] multidimensionalCoord)

Get the evidence linear coordinate from the multidimensional one. It basically ignores the target node (for now just one). LinearCoord = SumOf(StateOf[i] * FactorOf[i]), for all possible evidence nodes (i).

Parameters:

multidimensionalCoord - Multidimensional coordinate (represented by the state for each node).

Returns:

The corresponding evidence linear coordinate.

getMultidimensionalCoord

protected final int[] getMultidimensionalCoord(int linearCoord)

Get the multidimensional coordinate from the linear one.

Parameters:

linearCoord - The linear coordinate.

Returns:

The corresponding multidimensional coordinate.

init

protected void init(List<String> targetNodeNameList,
                    List<String> evidenceNodeNameList)

It creates the target and evidence node list of TreeVariable and the product of the target, evidence and total states.

Parameters:

targetNodeNameList - List of the target nodes name.

evidenceNodeNameList -

loadNetwork

Specified by:

getCurrentProgress in interface ILongTaskProgressObservable

Returns:

the current number of this long task progress. It represents a percentage.

getPercentageDone

public int getPercentageDone()

Description copied from interface: ILongTaskProgressObservable

Returns the percentage of the progress done so far. It should be Math.round((float)currentProgress / maxProgress * 10000), a number between 0 and 10000.

Specified by:

getPercentageDone in interface ILongTaskProgressObservable

Returns:

the percentage of the progress done so far.

updateProgress

protected void updateProgress(int progress,
                              String progressStatus)

As this progress is an approximation, it is going to be updated until it reaches 98%. Then the progress is not going to be updated anymore to avoid getting to 100% before the task is done.
