P. 1–4.
Gazizov R., Gazizov R., Gazizov T.
The paper presents the circuit diagram and the parameters of the cross-section for the model of the power supply (PS) bus of a spacecraft. The optimization of the duration of an ultrashort pulse (USP) exiting the PS bus was made by genetic algorithm(GA) for minimizing the voltage maximum along the PS bus. The GA optimization was run 10 times with every set of chromosomes and populations. The graphs of results convergence are presented for every set of GA parameters. The results of these investigations may be useful for estimating the worst case of USP excitation.

For a rapid area coverage multiple UAVs are often used simultaneously. However, a path planning for a UAVs group
during an area coverage task is computationally challenging. In practice, heuristic algorithms are applied to solve this
problem. This paper overviews approaches to an area coverage problem with a group of UAVs using genetic
algorithms. The article explores modifications ...
