Observers¶
It is possible to attach any number of observers to a jMetalPy’s algorithm to retrieve information from each iteration. For example, a basic algorithm observer will print the number of evaluations, the objectives from the best individual in the population and the computing time:
basic = BasicAlgorithmObserver(frequency=1.0)
algorithm.observable.register(observer=basic)
A full list of all available observer can be found at jmetal.component.observer
module.
