“…Several methods are proposed for the formation of user pairs such as round robin [28]. As these approaches tend to require significantly higher computational loads when the number of users increases, new computationally lower schemes have been proposed in literature to determine the user pairs such as the heuristic models which are inspired by artificial intelligence approaches [29][30][31][32][33][34] which include drosophila optimization algorithm [35], particle swarm optimization algorithm [36][37][38], firefly optimization algorithm [39], dolphin echolocation algorithm [40], genetic algorithm [20,41] and ant-colony optimization algorithm [19,42]. These models have the ability to solve problems in varying fields such as, but not limited to, transportation, signal processing, image processing and biomedical engineering.…”
