Algorithm 2 Weighted Average of FOs
Input: FOs $\mathit{\omega }={\{{\mathit{\omega }}_r\}}_{r=1}^R$ to average; weights $\mathit{\gamma }={\{{\gamma }_r\}}_{r=1}^R$ of the FOs; the current FO ωmp
Output: Averaged FO ω̄
1:	ω̄ ← 0
2:	for r = 1 : R do
3:	if ${\mathit{\omega }}_r^T{\mathit{\omega }}_{mp}<0$ then
4:	ωr ← −ωr
5:	end if
6:	ω̄ ← ω̄ + γrωr
7:	end for
8:	return $\overline{\mathit{\omega }}\leftarrow \frac{\overline{\mathit{\omega }}}{{\Vert \overline{\mathit{\omega }}\Vert }_2}$
