In this paper, we investigate and compare, through extensive simulation, the use of three meta-heuristic algorithms in order to find ‘‘good’’ feasible solutions for the global topology planning problem of universal mobile telecommunications system (UMTS) networks. The latter has been shown to be NP-hard as it is composed of three different subproblems (each(More)
In this paper, we propose a new cooperative algorithm based on tabu search (TS) and genetic algorithm (GA) in order to solve the global planning problem of Universal Mobile Telecommunications System (UMTS) networks. This problem has been shown to be NP-hard as it is composed of three different subproblems (each one being NP-hard): the cell planning problem,(More)
