- check_objective_decomposition: bei LP/MILP/CP muss eine objective_column den Zielwert
belegen, eine abweichende Beitragsspalte ist überall ein Befund -> Solver-Reparatur,
bleibt es: Warnung. 90 von 90 linearen Läufen seit 17.09. hätten bestanden.
- Summenzeilen: „Gesamt…“/„Nutzen…“ nur noch in der letzten Zeile, einzelne Zeile nie,
Zwischensummen nicht gegen die Gesamtsumme. Vorher 15 Rucksack-Läufe mit falschem
„Summe (0) weicht vom Zielwert (51) ab“; von 17 Abweichungen bleibt 1 echte.
- SOLVER_TIMEOUT (Default 60) für alle Programmläufe und als {ZEITLIMIT} im Solver-Prompt
- Benchmark: dirty zählt nur versionierte Dateien; SOLVER_TIMEOUT in der Konfiguration
Ändert die Prompt-Kennung (Solver-Prompt.txt).
