Procedure 2.1:

Step 0: $S^{\prime }=0$

Step 1: Identify $\Omega$ for which problem (2) is feasible and optimum such that $\Omega \in S$, or else go to step 4.

Step 2: If objective function (Problem (2))$>(1-\alpha )$ then $S^{\prime }=S^{\prime }+\left\{\Omega \right\},S=S-\left\{\Omega \right\}$, or else go to step 4.

Step 3: Go to step 1.

Step 4: Stop.
