Step 1:  Obtaining an optimal solution for the Reference case  
Step 2:  Iterative computation  
 Step 21:  Set 
 Step 22:  Generate a uniformly distributed random number on for 

 Define edge capacities as 

 if otherwise 
 Step 23:  Solve the above optimization problem. Obtain an optimal solution, , , 
 Step 24:  If, then end; otherwise Go to step 22 
Step 3:  Find the distribution for all solutions, , ,
