Channel Assignment Problems (CAPs) occur in the design of cellular mobile telecommunication systems (Jordan, 1996; Katzela and Naghshineh, 1996; MacDonald, 1979); such systems typically divide the geographical region to be serviced into a set of cells, each containing a base station. The available radio frequency spectrum is divided into a set of disjoint channels; these must be assigned to the base stations to meet the expected demand of each cell and to avoid electromagnetic interference during calls | Telecommunications Optimization Heuristic and Adaptive Techniques.

Debuse Michael D. Ryan and Iain M. Whittley Introduction Channel Assignment Problems CAPs occur in the design of cellular mobile telecommunication systems Jordan 1996 Katzela and Naghshineh 1996 MacDonald 1979 such systems typically divide the geographical region to be serviced into a set of cells each containing a base station. The available radio frequency spectrum is divided into a set of disjoint channels these must be assigned to the base stations to meet the expected demand of each cell and to avoid electromagnetic interference during calls. There are many different approaches to assigning channels to these base stations to achieve these objectives. The most commonly used technique is the Fixed Channel Assignment FCA scheme in which channels are assigned to each base station as part of the design stage and are essentially fixed in that no changes can be made to the set of channels available for a cell. There are also Dynamic Channel Assignment DCA schemes in which all of the available channels are stored in a common pool each new call that arrives in a cell is assigned a channel from this pool as long as it does not interfere with existing channels that are currently in use see Katzela and Naghshineh 1996 . There are also hybrids of FCA and DCA schemes as well as other variants such as Channel Borrowing methods. It has been shown that DCA schemes beat FCA schemes except under Telecommunications Optimization Heuristic and Adaptive Techniques edited by D. Corne . Oates and .
