Abstract

Falls Sie einen Regatta Flight Plan erzeugen wollen, wobei

  • kein Segler gegen einen anderen zu häufig antritt
  • kein Segler ein Boot zu häufig zugewiesen bekommt
  • möglichst kein Segler in aufeinanderfolgenden Flights segeln muss

dann hilft Ihnen hoffentlich dieses Programm:

sbregattaflightplan

Appendix – Programmcode sbRegattaFlightPlan

Bitte beachten: Dieses Programm benötigt (verwendet) die Klasse SystemState und die Funktion VBUniqRandInt.
