WebAbstract. We present iterative methods for finding the critical points and/or the minima of extended real valued functions of the form ϕ = ψ + g − h, where ψ is a differentiable function and g and h are convex, proper, and lower semicontinuous. The underlying idea relies upon the discretization of a first order dissipative dynamical system ... WebSep 9, 2024 · This paper proposes a coordinate descent method for minimizing a class of DC functions based on sequential nonconvex approximation. Our approach iteratively solves a nonconvex one-dimensional subproblem globally, and it is guaranteed to converge to a coordinate-wise stationary point.
