Verbessern der Organisation und Leistungsfähigkeit bei einer problembasierten Konfiguration

Umsetzen von Spezialaufgaben bei einer problembasierten Konfiguration

Diese Kategorie enthält Einzelheiten zu problembasierten Lösungen und bietet Anregungen für Spezialaufgaben. Informationen zu grundlegenden Tasks und einführenden Workflows finden Sie unter Erste Schritte mit der problembasierten Optimierung und Gleichungslösung.

Im ersten Abschnitt werden Möglichkeiten zur Leistungsoptimierung bei der Erstellung oder Feinabstimmung eines Problems erörtert.
Im zweiten Abschnitt wird erläutert, wie sich die Leistung verbessern lässt, wenn eine Zielfunktion oder Nebenbedingung for-Schleifen enthält.
Im dritten Abschnitt finden Sie Tipps für den effektiven Einsatz des problembasierten Ansatzes.
