Candidates who master shortcut methods and practice a wide range of variations can solve them quickly and accurately. Regular practice not only improves speed but also reduces the chances of confusion ...

Abstract: Nonlinear equations systems (NESs) are widely used in real-world problems and they are difficult to solve due to their nonlinearity and multiple roots. Evolutionary algorithms (EAs) are one ...

Abstract: In this note, we apply a hierarchical identification principle to study solving the Sylvester and Lyapunov matrix equations. In our approach, we regard the unknown matrix to be solved as ...
