Fractional programming (FP) plays a crucial role in wireless network design because many relevant problems involve maximizing or minimizing ratio terms. Notice that the maximization case and the ...

Mathematics of Operations Research, Vol. 41, No. 2 (May 2016), pp. 442-465 (24 pages) In view of solving nonsmooth and nonconvex problems involving complex constraints (like standard NLP problems), we ...

To overcome these challenges, we first prove that the optimal beamforming structure is the same for both the power minimization problem and the sum rate maximization problem, and then mathematically ...

Moreover, according to the energy maximization strategy, duration of grazing would be independent of size, while according to the time minimization strategy a positive correlation of grazing activity ...
