A conflict avoidance approach based on memetic algorithm under 4D-trajectory operation concept

• Through the experiment, we have prove that under 4DT environment, SCAMA has ability to give a feasible solution for conflict avoidance. • By contrast, it shows that our approach outperforms the existing approaches. Our approach´s solution has no conflict and less delay. • When the scale increases, our approach also performs well. It has show its good ability in solving large-scale combinatorial optimization problem like this.
