- Abstract
- Das Problem der kürzesten Rundreise ist Prototyp einer großen Klasse praktisch bedeutsamer, komplexer Minimierungs- und Maximierungsaufgaben. Sie sind so schwer, daß man sich häufig mit einer brauchbaren Näherung zufrieden geben muß. Neue, listenreiche Verfahren liefern jedoch immer häufiger die nachweislich beste Lösung
