Abstract :
The adaption of meta-heuristic algorithms such as tabu search and simulated annealing to large frequency assignment problems with complex co-site constraints is described. The constraints considered include frequency separation constraints, intermodulation product constraints and spurious emission and response constraints. Requests for frequencies can also be prioritised. The importance of fast evaluation of the quality of the current assignment by updating techniques is stressed. Additionally, a useful lower bound for assessing the quality of assignments is described
