| - **Nonsmooth Convex Optimization Problem**:\\ It assumes that $f^{(i)}$ $(i\in \mathcal{I})$ is nonsmooth and convex. The problem includes [[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=4407760&filter%3DAND%28p_IS_Number%3A4407756%29|signal recovery problem]],[[https://ieeexplore.ieee.org/document/8744480|ensemble learning]], [[http://link.springer.com/chapter/10.1007/978-1-4419-9569-8_17|minimal antenna-subset selection problem]], and [[https://ieeexplore.ieee.org/document/8584116|bandwidth allocation problem]]. | - **Nonsmooth Convex Optimization Problem**:\\ It assumes that $f^{(i)}$ $(i\in \mathcal{I})$ is nonsmooth and convex.
