The aim of the Workshop is to review and discuss recent developments of the theory of Nonsmooth Analysis and Optimization and to provide a forum for fruitful interaction in closely related areas. Nonsmooth problems appear in many fields of applications, such as data mining, image denoising, energy management, optimal control, neural network training, economics and computational chemistry and physics. Motivated by these applications Nonsmooth Analysis has had a considerable impulse that allowed the development of sophisticated methodologies for solving challenging related problems.
