Comparison of constrained optimization methods for designing a multi-bend achromat lattice
Journal of Physics, Conference Series
In the design of a multi-bend achromat (MBA) lattice for a diffraction-limited storage ring, there are usually many magnet parameters to be optimized and some stringent constraints to be satisfied. For example, to cancel out nonlinear dynamics effects, the phase advances between some sections are generally required to be set to certain values in the lattice design. For better designing a MBA lattice using an evolutionary algorithm, the handling of constraints will be important, because it isdoi:10.1088/1742-6596/1350/1/012032 fatcat:v7ruzjj6qrauvkezx62o6tmcq4
