title = "De-Σ: A modified differential evolution algorithm",
abstract = "A modified version of the differential evolution (DE) algorithm, designated as DEΣ, employs an additive component for some of the trial solutions. This algorithm has been further refined to reduce the probability of stagnation. The algorithm is applied to a trajectory optimization problem (determining optimal steering strategies for a two-arc low-thrust orbital transfer) and the results compared with those using particle swarm optimization (PSO). The new version of DE-Σ shows no instances of stagnation in the test cases, and requires only 7% more computation time than PSO.",
