Summary

Let be given a weighted complete graph. We look for a clique of given cardinality and with minimal cost. This problem arises when selecting facilities so as to minimise their average distance. Two heuristic solution methods prove to be encouraging and are numerically compared with respect to efficiency.

Zusammenfassung

Gegeben sei ein vollständiger, bewerteter Graph. Gesucht ist eine kostenminimale Clique mit vorgegebener Kardinalität. Dieses Problem tritt bei der Auswahl von Standorten auf, wenn deren durchschnittliche gegenseitige Entfernung zu minimieren ist. Zwei heuristische Lösungsverfahren erweisen sich als günstig und werden bezüglich ihrer Wirksamkeit numerisch verglichen.
