Optimal structure and efficient algorithm for max-min fair multi-group multicast beamforming
… subject to transmit power limit. We obtain the optimal multicast beamforming solution structure for an arbitrary system configuration. We show that the optimal MMF solution has a weighted minimum mean square error (MMSE) filter structure and a similar structure to that of the quality-of-service …

Efficient design of reconfigurable intelligent surface assisted multi-group multicast beamforming
… (AMBA) not only enables us to exploit the optimal multicast beamforming structure at the BS, but also allows us to employ a fast first-order projected subgradient algorithm (PSA) to solve the RIS MMF subproblem. Furthermore, we show that QoS problem and MMF problem in our RIS-aided scenario …

New numerical methods for open-loop and feedback solutions to dynamic optimization problems
… method that relies on a group of potential solutions to explore the fitness landscape. Conceptually, each particle in the swarm uses its own memory as well as the knowledge accumulated by the entire swarm to iteratively converge on an optimal or near-optimal solution. It is relatively …
