com.decs.application.engines.EvolutionEngine

All Implemented Interfaces:

Runnable

public class EvolutionEngine
extends Thread

Evolution Engine Class

This class represents the system's evolution engine. The engine manages all evolutionary operations and establishes a bridge between DECS and ECJ engine. Since its operations are resource-intensive, it is processed concurrently.

 JobDashboardView jobDashboard,
 SlaveManager slaveManager,
 Timer timer,
 SessionManager sessionManager,
 String[] args)

Evolution engine class constructor

Parameters:

paramsFile - Main parameters file

job - Job object to be processed

ui - Main Vaadin UI object

jobDashboard - Job dashboard view object

slaveManager - Slave manager object

timer - Timer object

sessionManager - Session manager object

args - Command line arguments

Method Details

run

public void run()

Engine thread starting point

It is responsible for the initial configuration and inference initialization.

Specified by:

run in interface Runnable

Overrides:

run in class Thread

startInference

public void startInference()

Inference initialization

This method processes all internal evolutionary operations required for a solution to be found and it interacts directly with ECJ's API.

cleanup

private void cleanup(ec.EvolutionState evaluatedState)

Cleans and resets the evolutionary engine

Parameters:

evaluatedState - Object that represents the evolution state
