Class BehaviorsWTA

java.lang.Object

br.unicamp.cst.core.entities.Codelet

br.unicamp.cst.behavior.bn.BehaviorsWTA

All Implemented Interfaces:

MemoryObserver, java.lang.Runnable

public class BehaviorsWTA
extends Codelet

This codelet implements a "winners take all" mechanism for the behavior network. It takes a number of behaviors and make the one with the highest activation level ACTIVE.

Constructor Detail

BehaviorsWTA

public BehaviorsWTA(GlobalVariables globalVariables)

Iterate over all behaviors. If none of them are ACTIVE, choose the one with highest activation and which is executable Make that one ACTIVE. Once it becomes active, its activation will drop to zero, but might remain active until it performs its job. I should only try to choose another one once they are all INACTIVE.

Method Detail

accessMemoryObjects

public void accessMemoryObjects()

Description copied from class: Codelet

This method is used in every Codelet to capture input, broadcast and output MemoryObjects which shall be used in the proc() method. This abstract method must be implemented by the user. Here, the user must get the inputs and outputs it needs to perform proc.

Specified by:

accessMemoryObjects in class Codelet

proc

public void proc()

Description copied from class: Codelet

Main Codelet function, to be implemented in each subclass.

Specified by:

proc in class Codelet

addBehavior

public void addBehavior(Behavior be)

removeBehavior

public void removeBehavior(Behavior be)

calculateActivation

public void calculateActivation()

Description copied from class: Codelet

This abstract method must be implemented by the user. Here, the user must calculate the activation of the codelet before it does what it is supposed to do in proc();

Specified by:

calculateActivation in class Codelet
