 The SR algorithm determines the most optimal solution still using the outcomes of SE, by implementing a Multiple-Criteria Decision Analysis (MCDA) approach, which considers as objectives the simultaneous minimization of (i) total power losses and (ii) the utilization of electrical lines $`\theta_{x,y}`$. This latter aspect indicates the current that can still flow in a line in relation to its maximum value and is computed as:<br>
