| contents | In this paper, we study an explicit Tikhonov-regularized inertial gradient algorithm for smooth convex minimization with Lipschitz continuous gradient. The method is derived via an explicit time discretization of a damped inertial system with vanishing Tikhonov regularization. Under appropriate control of the decay rate of the Tikhonov term, we establish accelerated convergence of the objective values to the minimum together with strong convergence of the iterates to the minimum-norm minimizer. In particular, for polynomial schedules $\varepsilon_k = k^{-p}$ with $0<p<2$, we prove strong convergence to the minimum-norm solution while preserving fast objective decay. In the critical case $p=2$, we still obtain fast rates for the objective values, while our analysis does not guarantee strong convergence to the minimum-norm minimizer. Furthermore, we provide a thorough theoretical analysis for several choices of Tikhonov schedules. Numerical experiments on synthetic, benchmark, and real datasets illustrate the practical performance of the proposed algorithm. |
