Asteroid Rendezvous Mission Design Using Multiobjective Particle Swarm Optimization

Algorithm 1

Begin

 For each swarm

  (1) Initialize its particles

  (2) Initialize the set of global leaders: 𝑔_leader

 End For

 DO

  For each swarm

    Do

     For each particle

      (3) Select a leader

      (4) Perform the flight

      (5) Update the value

      If it is a leader then add to the 𝑔_leader

   End For

    While (number of iterations ≤ sgmax)

    (6) Store leaders in 𝑔_leader in 𝑛_swarmsgroups

  End For

  (7) Assign each leader group to a swarm

 While (number of iterations ≤ GMax)

End
