GPSPSOCCHJ

public GPSPSOCCHJ(GenOpt genOptData)
           throws OptimizerException,
                  java.io.IOException,
                  java.lang.Exception,
                  InputFormatException

Constructor

Parameters:

genOptData - a reference to the GenOpt object.
Note: the object is used as a reference. Hence, the data of GenOpt are modified by this Class.

Throws:

OptimizerException - if an OptimizerException occurs or if the user required to stop GenOpt

SimulationInputException - if an error in writing the simulation input file occurs

java.lang.NoSuchMethodException - if a method that should be invoked could not be found

java.lang.IllegalAccessException - if an invoked method enforces Java language access control and the underlying method is inaccessible

InvocationTargetException - if an invoked method throws an exception

java.lang.Exception - if an I/O error in the simulation input file occurs

java.io.IOException

InputFormatException

Method Detail

run

public int run(Point x0)
        throws SimulationInputException,
               OptimizerException,

               java.lang.IllegalAccessException,
               java.lang.Exception

Runs the optimization process until a termination criteria is satisfied

Overrides:

run in class ModelPSO

Parameters:

x0 - initial point

Returns:

-1 if the maximum number of iteration is exceeded
+1 if the required accuracy is reached

Throws:

OptimizerException - if an OptimizerException occurs or if the user required to stop GenOpt

SimulationInputException - if an error in writing the simulation input file occurs

java.lang.NoSuchMethodException - if a method that should be invoked could not be found

java.lang.IllegalAccessException - if an invoked method enforces Java language access control and the underlying method is inaccessible

InvocationTargetException - if an invoked method throws an exception

java.lang.Exception - if an I/O error in the simulation input file occurs
