Summary
| Description |
English: Performance landscape showing how a simple Particle Swarm Optimization (PSO) variant performs in aggregate on several benchmark problems when varying two PSO parameters. Lower meta-fitness values means better PSO performance. Such a performance landscape is very time-consuming to compute, especially for optimizers with several behavioural parameters, but it can be searched efficiently using the simple meta-optimization approach by Pedersen implemented in SwarmOps to uncover PSO parameters with good performance. Good choices would here seem to be in the region and , and the region and Deutsch: Gütefunktion, die zeigt wie gut eine einfache Variante der Partikelschwarmoptimierung (PSO) verschiedene Testfunktionen unter Veränderung zweier Parameter insgesamt bearbeitet. Ein kleinerer Meta-Fitness-Wert bedeutet eine bessere Performance der PSO. Eine gute Parameterwahl läge hier in der Region und , und in der Region und |
