org.uma.jmetal.util.observer.impl.RunTimeForDynamicProblemsChartObserver<S>

All Implemented Interfaces:

Observer<Map<String,Object>>

public class RunTimeForDynamicProblemsChartObserver<S extends Solution<?>>
extends Object
implements Observer<Map<String,Object>>

This observer prints a chart in real time showing the current Pareto front approximation produced by an algorithm. It requires a two pairs in the map used in the update() method: * - (EVALUATIONS, int) * - (POPULATION, List)
