FOCUS-HTS: a new stellarator coil design code for three-dimensional high-temperature superconducting magnets

Nuclear Fusion
Stellarators mainly utilize magnetic fields from external coils to confine the plasma, enabling steady-state operation while avoiding instabilities like disruptions raised from plasma currents.

Stellar Flare Optimization Algorithm

Various physical phenomena in nature provide a wealth of heuristic inspiration for optimization algorithms. This paper proposes a new heuristic optimization algorithm based on the stellar flare phenomenon, the Stellar Flare Optimization Algorithm (SFOA). This algorithm achieves efficient search for complex optimization problems by simulating the sudden
