Algorithm 1 (Bisection algorithm to solve P7 if Equation (12) is active)

Require: Initialize ${\mu }_l$ and ${\mu }_u$, set ${ϵ}_1>0$.   repeat          1. Set $\mu =({\mu }_l+{\mu }_u)/2$.          2. Compute $\mathbf{s}\left(\mu \right)$ via (21).          3. If $\tilde{g}(\mathbf{s}\left(\mu \right)/\tilde{\mathbf{s}}))\ge \widetilde{P_I}$, set ${\mu }_l=\mu$, otherwise set ${\mu }_u=\mu$.   until$|{\mu }_u-{\mu }_l|\le {ϵ}_1$.   4. Output $\mathbf{s}\left(\mu \right)$ as the global optimal solution of P7.
