This work concentrates on optimization on Riemannian manifolds. The Limited-memory Broyden–Fletcher–Goldfarb–Shanno (LBFGS) algorithm is a commonly used quasi-Newton method for numerical optimization ...

Most optimization algorithms are based on quadratic approximations to nonlinear functions. You should try to avoid the use of funcions that cannot be properly approximated by quadratic functions. Try ...

Phase modulation jamming (PMJ) alters the characteristics of radar echo signals through multiplicative time-varying phase modulation, thereby degrading the performance of conventional radar signal ...
