Secondly, a decision criterion is proposed to determine whether one HF experiment or several LF experiments with the equivalent computational cost should be selected to update the MF metamodel.
It also requires a little coordination among the relays to determine which relay is selected to update its beamforming vector in each iteration.
Beamforming vector: a relay k is randomly selected to update f X, k ( n ) = ν max ( Y BF, k ( F X ( n − 1 ) ) ).
where w ̃ Ḟ ( n ) are the weights that are not selected to update and we know w ̃ Ḟ ( n + 1 ) = w ̃ Ḟ ( n ) (37).
Beamforming vector: a relay k is randomly selected to update f X, k ( n ) = ν max ( Y BF, k ( F X ( n − 1 ) ) ). Initialization: each relay k feeds forward ϕ k ( ξ ̄ k, t ) to receiver k and selects a random beamformer f X, k ( 0 ).
Beamforming vector: a relay k is randomly selected to update f X, k ( n ) = ν max ( Y BF, k ( F X ( n − 1 ) ) ). Interference price: each receiver k computes θ BF, ip 1, k ( F X ( n − 1 ) ) and broadcasts to all the relays.
As discussed in[19], we only need to show that U1(n) is monotonically increasing, i.e., it suffices to consider a given iteration n in which user q is selected to update its power profile, and show that U1(p q (n + 1)) ≥ U1(p q (n)), where the total utility U1 is now regarded as a function of p q because only the power profile of user q is updated.
The Mair et al 14 systematic review was selected to update as it is the primary review in the area of e-health implementation.
In the GA method, a node is randomly selected to be updated at every time step; unlike in the ROA update scheme, a node in the GA update scheme may be updated twice before every node is updated once.
At each time step, rather than updating all species, some species are randomly selected to be updated, while the unselected species are left in their current state.
Thus, in each sub-filter the filter coefficients corresponding to the ⌊Q·L⌋ largest magnitude tap-inputs are selected to be updated in every frame.
