A review of Hybrid/combined methods for trajectory optimization of flight vehicles

Abstract This work aims to review the proposed trajectory optimization algorithms and their applications in solving flight planning optimal control problems. Beside classification of listed Chai R, Savvaris A, Tsourdos A S such as deterministic; stochastic; multi-objective algorithms, this adds reviewing effective frequently-used approach for problems— hybrid/combined methods. The results related works show that hybrid is can provide feasible solutions vehicle design
