Abstract

Addressing optimization problems using the finite-time/fixed-time stability properties of dynamical systems has received increasing interest. In this work, we propose new fixed-time second-order time-varying dynamical systems. We derive a sufficient condition for the existence and uniqueness of solutions to a general ordinary differential equation (ODE) and present a rigorous proof establishing the well-posedness of our proposed algorithms, addressing a significant gap in the literature. We then employ the proposed dynamical systems to solve nonsmooth additive composite optimization problems.
