java.lang.Object
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)
