Fireworks Algorithm for Frequency Assignment Problem
Proceedings of the 3rd International Conference on Networking, Information Systems & Security, 2020In this paper, a new approach to resolve the problem of frequency assignment problem is proposed. (FAP) is well known in the NP-complete problems and can be modeled as an optimization problem, which the objective is to minimize the costs due to interference generated by a solution. The fireworks algorithm (FWA) is proposed for solving FAP.

Measuring the Effectiveness of Frequency Assignment Algorithms
IEEE Transactions on Vehicular Technology, 2007Lower bounds are used to assess the quality of frequency assignments and the effectiveness of the algorithms used to obtain them. This paper makes three contributions. First, a technique is described for modifying an effective existing lower bound for the span to take account of multiple interference. Multiple interference may increase the span and the

An ANTS heuristic for the frequency assignment problem
Future Generation Computer Systems, 2000Abstract The problem considered in this paper consists in assigning frequencies to radio links between base stations and mobile transmitters in order to minimize the global interference over a given region. This problem is NP-hard and few results have been reported on techniques for solving it to optimality.

Assigning Frequencies in GSM Networks
2003Mobile communication is a key technology in today’s information age. Despite the ongoing improvements in equipment design, interference remains a limiting factor for the use of radio communication. The author investigates in his PhD thesis how to largely prevent interference in GSM networks by carefully assigning the available frequencies to the ...

The term frequency assignment has been used to describe many types of problems which, quite often, have different modeling needs and objectives. These problems include: 1. Planning models for permanent spectrum allocation, licensing, and regulation which maximize utilization of all radio spectra [94]. 2.

An Approach to Frequency Assignment
IEEE Transactions on Electromagnetic Compatibility, 1966Frequency assignment should be based on minimization of the unwanted interactions between equipment in an environment. An approach to this problem is developed, based on the operations research technique known as dynamic programming. The basic tools required are an interference prediction model that is capable of providing relative values and a means ...

Elementary landscapes of frequency assignment problems
Proceedings of the 12th annual conference on Genetic and evolutionary computation, 2010We analyze various forms of the Frequency Assignment Problem using the theory of elementary landscapes. We show that three variants of the Frequency Assignment Problem are either directly an Elementary Landscape, or are a superposition of two Elementary Landscapes. We also examine the computability of neighborhood averages for partial neighborhoods.
