The flow chart of the simulation and optimization utilized in the present study to derive the feasible stability region boundaries. Simulated annealing algorithm (SAA) was adopted to conduct the optimization portion. The iteration was terminated when the improvement in the cost function was less than 10-3 for 500 consecutive function evaluations. Also shown are the values of the weights employed in the cost function.
