Constructor Details

Algorithm

public Algorithm(String name,
 String reference,
 Execution exe)

Constructor of an Algorithm given the name, the publication reference and the current configuration of the execution.

Parameters:

name - name of the Algorithm.

reference - reference of the publication of the Algorithm.

exe - configuration of the current execution.

Method Details

run

public Individual run()
               throws IncompatibleConfigurationException

Runs an execution of the algorithm after an initialization process of its components.

Returns:

Individual representing the solution of the optimization process.

Throws:

IncompatibleConfigurationException - if an incompatibility is detected.

runAlgorithm

protected abstract Individual runAlgorithm()
                                    throws IncompatibleConfigurationException

Runs the algorithm over the defined configuration.

Returns:

Individual representing the solution of the optimization process.

Throws:

IncompatibleConfigurationException - if an incompatibility is detected.

initAlgorithmParams

protected abstract void initAlgorithmParams()

Executed before running an execution of the Algorithm, it is the place were the initialization process of the components which are going to be used by the Algorithm takes place.

getName

public String getName()

Gets the name of the Algorithm.

Returns:

the name of the Algorithm.

getReference

public String getReference()

Gets the publication reference of the Algorithm.

Returns:

the publication reference of the Algorothm.

toString

public String toString()

Gets a string representing the visualization by console of the Algorithm.

Overrides:

toString in class Object

Returns:

the name of the Algorithm.
