TierCEM: Prioritätsgesteuerte Constraint-Relaxation für die Cross-Entropy-Optimierung

Francisco Roldan Sanchez, Pau de las Heras Molins, David Fridovich-Keil, Georgios Bakirtzis

Das Preprint stellt TierCEM vor, eine Variante der Cross-Entropy-Methode, die eine strikte Prioritätsreihenfolge von Constraints direkt in die Elite-Auswahl integriert und ohne per-Constraint-Gewichte auskommt. In Simulationen mit 2D-Navigation und Push-T zeigt die Methode, dass sich beim Umkehren der Prioritätsreihenfolge gezielt die verletzte Constraint ändert und dass die Aufgabenpriorität Fortschritt erzwingen kann, wenn Constraints sonst zum Stillstand führen. Damit adressiert sie das Problem, dass gewichtete Strafformulierungen höher priorisierte Verletzungen durch niedrigere kompensieren können.
