We also plot the allocated powers under the optimal power allocation policy in the bottom panel of Figure 8.
We plot the allocated powers in the top panel of Figure 8.
With the optimal total transmission power and the allocated powers at hand, the transmission completion time can be determined.
Otherwise, the allocated powers can be increased to improve the objective value, that contradicts the optimality assumption.
The optimal allocated powers are determined by selecting the transmission powers (P1,..., P L ) ∈ Ψ L that maximize Equation (13) under the constraints given in Equation (12).
Moreover, since the objective function is an increasing function of the allocated powers, the inequality constraints (6b) should be met with equality at optimality.

(ii) Obtain total allocated power for each user,.
It also indicates that decreasing allocated power may improve EE.
In Figure 2, we consider the allocated power over iterations.
The scheduled users are allocated power to guarantee successful separation at the detector by successive decoding.
Note that there exists at least one relay which has nonzero allocated power at optimality.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
