Zsfassung in dt. SpracheDas Minimum Label Spanning Tree Problem ist ein kombinatorisches Optimierungsproblem mit Anwendungen im Bereich des Designs von Telekommunikationsnetzwerken. Gegeben ist ein zusammenhängender Graph, wobei jeder Kante ein oder mehrere Label zugewiesen sind. Das Ziel ist die Bestimmung eines Spannbaumes welcher eine minimale Anzahl an Labels benötigt. Dabei muss für jede gewählte Kante mindestens ein Label ausgewählt werden. Das Problem ist NP-vollständig.Die bisherige Forschung in Bezug auf das gegebene Problem war primär auf die Entwicklung approximativer und metaheuristischer Algorithmen ausgerichtet, aber auch exakte Verfahren wurden vorgeschlagen. Es wurde gezeigt, dass kein polynomieller Algorithmus mit konstante...
