@Deprecated
public class IsReachableShortestPebblePathAaronModified
extends EfficientPebbleAlgorithm

This algorithm uses BFS to find the shortest path to the source (target) vertex. It accounts for paths with pebbles, so if a vertex has a pebble on it this algorithm does not increment the distance through that vertex. Using a weight array, this algorithm can quickly determine if the source is reachable by comparing the number of pebbles on a vertex to its corresponding weight. The weight for a vertex is based on the weight of its parent and the number of pebbles on its parent.

Modifier and Type	Method and Description
java.lang.String	argumentFormat() Deprecated. Describe how the argument(s) to the algorithm should be formatted, if applicable.
boolean	countsOperations() Deprecated.
double	getVersion() Deprecated. Mostly for use in comparing results from previous versions of algorithms, and/or so we can know whether or not data in the database is based on an older version of the algorithm.
void	initializeMoreData() Deprecated. Called by initializeData which is called by setPuzzleData.
void	parseArguments(java.lang.String args) Deprecated. Sends a string that the user can enter to the algorithm.
void	reinitializeMoreData() Deprecated. If resetWithThesePebbles is called, what else needs to be reinitialized before the algorithm can be run? This is supposed to be much more efficient than calling initializeMoreData.
void	resetWithThesePebblesAndNewSource(int[] newPebbles, int newSource) Deprecated.

Method Detail

initializeMoreData

public void initializeMoreData()

Deprecated.

Description copied from class: PebbleAlgorithm

Called by initializeData which is called by setPuzzleData. It should initialize data in the subclass that needs it.

Overrides:

initializeMoreData in class EfficientPebbleAlgorithm

reinitializeMoreData

public void reinitializeMoreData()

Deprecated.

Description copied from class: EfficientPebbleAlgorithm

If resetWithThesePebbles is called, what else needs to be reinitialized before the algorithm can be run? This is supposed to be much more efficient than calling initializeMoreData. The idea is that the graph didn't change, but the data did, so we only need to reinitialize some things.

Specified by:

reinitializeMoreData in class EfficientPebbleAlgorithm

resetWithThesePebblesAndNewSource

public void resetWithThesePebblesAndNewSource(int[] newPebbles,
                                              int newSource)

Deprecated.

runAlgorithm

public void runAlgorithm()

Deprecated.

Description copied from interface: AlgorithmInterface

Runs the Algorithm. This is the most important method.

countsOperations

public boolean countsOperations()

Deprecated.

Returns:

True if and only if the algorithm intends to keep track of the number of operations it is performing. Each algorithm is free to decide what it considers an "operation" to be.

getVersion

public double getVersion()

Deprecated.

Description copied from interface: AlgorithmInterface

Mostly for use in comparing results from previous versions of algorithms, and/or so we can know whether or not data in the database is based on an older version of the algorithm. Start with "return 1.0". Go up by whatever increments you like (e.g. 1.1, 1.2, etc. or 1, 2, 3, etc.)

Returns:

parseArguments

public void parseArguments(java.lang.String args)

Deprecated.

Description copied from interface: AlgorithmInterface

Sends a string that the user can enter to the algorithm. The string will be in whatever format the user enters. Implementation can assume this method is called after the problem data has been set. Throw an exception if different arguments are required.

argumentFormat

public java.lang.String argumentFormat()

Deprecated.

Description copied from interface: AlgorithmInterface

Describe how the argument(s) to the algorithm should be formatted, if applicable.

Returns:
