A consensus-based optimization method for nonsmooth nonconvex programs with approximated gradient descent scheme
Jiazhen Wei, Fan Wu, Wei Bian
In this paper, we are interested in finding the global minimizer of a nonsmooth nonconvex unconstrained optimization problem. By combining the discrete consensus-based optimization…

Extrapolated Hard Thresholding Algorithms with Finite Length for Composite Penalized Problems
Fan Wu, Jiazhen Wei, Wei Bian
For a class of sparse optimization problems with the penalty function of , we first characterize its local minimizers and then propose an extrapolated hard thresho…
