In several systems, including wireless communication ones, certain services, which are referred to as benefits, are provided to multiple users based on the allocation of shared resources that are typically scarce. The allocation of these resources typically encounters conflicting goals. For instance, favoring a certain class of users may increase the system's efficiency, but would result in the dissatisfaction of other classes of users. In contrast, providing equal benefits to all users may result in higher fairness, but will potentially result in low efficiency.
