In this paper we study a gradient-based continuous method for large-scale optimization problems. By converting the optimization problem into an ODE we are able to show that the solution trajectory of this ODE tends to the set of stationary points of the original optimization problem. We test our continuous method on large-scale problems available in the literature. The simulation results are very attractive.
