Figure 3From: Optimal resource allocation in wireless communication and networkingPrimal and dual iterates in dual stochastic gradient descent. Evolution of dual variables λ i (t) and rates r i (t) for representative nodes with average channelsE h 1 (t)=1 andE h 9 (t)=3 for the algorithm in (93)–(97) are shown. Multipliers λ i (t) and capacities c i (t) do not converge, but ergodic rates c ̄ i (t) do.Back to article page
