“…This paper deals with optimal control problems described by polyhedral discrete and differential inclusions with delay constraints, and this class of problems is truly challenging and underinvestigated in control theory while being highly important for various applications; Moreau's sweeping process and Von Neumann-Gale dynamical systems, etc. Note that these problems also occur not only in mechanics, aerospace engineering, management science, and economy but also automatic control, auto vibration, and biophysics [19,34,35].…”
