A Machine Learning Enhanced Algorithm for the Optimal Landing Problem [PDF]
arXiv, 2022 We propose a machine learning enhanced algorithm for solving the optimal landing problem. Using Pontryagin's minimum principle, we derive a two-point boundary value problem for the landing problem. The proposed algorithm uses deep learning to predict the optimal landing time and a space-marching technique to provide good initial guesses for the ...
