A new hybrid conjugate gradient algorithm based on the Newton direction to solve unconstrained optimization problems [PDF]

open access: yes, 2023
https://doi.org/10.1007/s12190-022-01821-zIn this paper, we propose a new hybrid conjugate gradient method to solve unconstrained optimization problems. This new method is defined as a convex combination of DY and DL conjugate gradient methods.

Performance Bounds For Co-/Sparse Box Constrained Signal Recovery

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
The recovery of structured signals from a few linear measurements is a central point in both compressed sensing (CS) and discrete tomography. In CS the signal structure is described by means of a low complexity model e.g. co-/sparsity.
