(Communicated by Jie Sun) In addressing the challenges of nonconvex, nonsmooth, and nonseparable optimization, this paper introduces a novel symmetric inertial Bregman Alternating Direction Method of Multipliers (SIBADMM). This algorithm extends the symmetric ADMM by incorporating an inertial mechanism and Bregman divergence within the x-subproblem, aiming to accelerate convergence. The asymptotic convergence is established under the assumption of boundedness in the sequence generated by the algorithm, utilizing the Kurdyka-Łojasiewicz property. The practical utility of SIBADMM is demonstrated through its application to various linear regression problems with different regularization terms, thereby showcasing its effectiveness.
