We propose and study a version of the DCA (Difference-of-Convex functions Algorithm) using the $\ell_1$ penalty function for solving nonsmooth DC optimization problems with nonsmooth DC equality and inequality constraints. The method employs an adaptive penalty updating strategy to improve its performance. This strategy is based on the so-called steering exact penalty methodology and relies on solving some auxiliary convex subproblems to determine a suitable value of the penalty parameter. We present a detailed convergence analysis of the method and illustrate its practical performance by applying the method to two nonsmooth discrete optimal control problem.
Comment: The second version of the paper was shortened and rewritten to simplify the understanding of the main results. The section containing the results of numerical experiments was completely rewritten and now includes some applications of the steering exact penalty DCA to 2 semi-academic nonsmooth discreet optimal control problems
