Machine Learning of Optimal Low-Thrust Transfers Between Near-Earth Objects
During the initial phase of space trajectory planning and optimization, it is common to have to solve large dimensional global optimization problems. In particular continuous low-thrust propulsion is computati...

PaDe: A Parallel Algorithm Based on the MOEA/D Framework and the Island Model
We study a coarse grained parallelization scheme (thread based) aimed at solving complex multi-objective problems by means of decomposition. Our scheme is loosely based on the MOEA/D framework. The resulting a...
