Class PredictionModifierOpt

java.lang.Object

network.modifiers.PredictionModifierOpt

All Implemented Interfaces:

NetworkModifier

public class PredictionModifierOpt
extends java.lang.Object
implements NetworkModifier

PredictionModifierOpt implement the NetworkModifier interface. It will modify the ranking by moving randomly chosen links up and down the ranking at each action. Both the amount of links to moved and how much they can move in the ranking are randomly determined within a certain range. It will alert the fitnessfunction if applicable that changes were made.

Constructs a new PredictionModifierOpt

Parameters:

wrapper - ranking object to be re-ranked, with a

modifyEachTurn - maximum amount of links that can be mofidied

moveEachTurn - maximum amount of positions a link can move up or down

Method Detail

modify

public void modify()

Implements the modify action of the interface. This method will alter the ranking by moving a certain amount of links up or down the rank as specified in the class description and manuscript. It will alert the fitnessfunction if applicable and set the flag of this class to modded state.

Specified by:

modify in interface NetworkModifier
