has been applied to simultaneously
minimize total NPC of the system, fuel emission and
maximize RER. The engaging advantage of this method is generating
a PF with higher quality than what is resulted by well-known
MOP approaches. The main idea of the proposed algorithm is that
multi-leaders and dynamic cell-based density calculation strategy
is utilized to update the solutions. Two methods usually are performed
to select leaders in guiding swarm flights: randomly selecting one of the best solutions or using multiple leaders
