Ersatzoptimierung
Ersatzoptimierungs-Solver für rechenintensive Zielfunktionen mit Schranken und optionalen ganzzahligen Randbedingungen
Verwenden Sie Ersatzoptimierung für aufwändige (zeitintensive) Zielfunktionen. Der Solver erfordert endliche Schranken für alle Variablen, erlaubt nichtlineare Ungleichungsbedingungen und akzeptiert ganzzahlige Beschränkungen für ausgewählte Variablen. Der Solver kann optional seinen Zustand nach jeder Funktionsauswertung speichern, um eine Wiederherstellung nach vorzeitigem Abbruch zu ermöglichen.
