Tabu Thresholding for the Frequency Assignment Problem

The frequency assignment problem is to allocate frequencies to communication links such that the total interference is minimised. In this paper we investigate a tabu thresholding procedure to solve the frequency assignment problem. Several variants of the method are implemented using large computer-generated but realistic data sets. We report on these investigations, the selection of suitable parameters and compare the method with a tabu search for the same problem. We conclude that, in the same amount of time, tabu thresholding provides better quality solutions than tabu search.
