Step 1: Generate initial population for leader’s Pop (Create random population (nPop));

Step 2: Evaluate population (nPop)) to create fitness values

Step 3: Sort ' 'leader's population and save the best solution;

Step 4:  While (Not termination condition) do:

Select P1 and P2 by roulette wheel selection;

Apply crossover to P1 and P2 and obtain two offspring's P′1 and P′2

Evaluate P′1 and P′2

Generate P (n+1) from P1 and P2, P′1 and P′2

Set n:=n+1

End.

Step 5: Stop.
