“…To cope with this issue, other approaches propose heuristic-based solutions (e.g., WS-HEU and WFlow [5], Genetic algorithm [8,9,6,7,10,11,12]) aiming to find near-optimal compositions, i.e., compositions that respect global QoS constraints and maximize a QoS utility function. Yu et al [5] present two heuristics, WS-HEU and WFlow, for the service selection problem.…”
