Computing critical velocities in waveguides via multiparameter eigenvalue problems
Hauke Gravenkamp, Xiang Liu
In waveguide dynamics and moving-load problems (e.g., high-speed trains), critical velocities indicate the onset of strong vibration amplification. In systems that are invariant in…

A Large-Scale Sparse Multiobjective Optimization Algorithm Based on Optimal Performance Scores
Jia-Lin Mai, Min-Rong Chen, Guo-Qiang Zeng +2
Large-scale sparse multiobjective optimization problems (LSSMOPs) involve a large number of decision variables and Pareto optimal solutions with only a few nonzero variables. Howev…
