Abstract

Process engineering applications often lead to non-smooth constrained optimization problems in which the objective function and/or the constraints have non-differentiabilities and step discontinuities. Since the objective function is often the outcome of a complex simulation or the outcome of a lower level optimization problem, it may also be noisy and not defined in some point.

In this work we propose and test a new hybrid ...
