In the areas of chemical processes and energy systems, the relevance of black-box optimization problems is growing because they arise not only in the optimization of processes with modular/sequential simulation codes but also when decomposing complex optimization problems into bilevel programs, or when optimizing. The objective function is typically discontinuous, non-differentiable, not defined in some points, noisy, and subject to linear and nonlinear relaxable and unrelaxable constraints.

Dr. Martelli, after briefly reviewing the main available derivative-free methods applicable to this class of problems, will present PGS-COM, the hybrid algorithm he recently developed with Prof. E. Amaldi, and its applications in the area of process engineering and energy systems. The algorithm combines the positive features of the Particle Swarm Optimizer, Generating Set Search, and Complex.

The performance of PGS-COM has been benchmarked against eleven state-of-the-art derivative-free methods and tested on several process engineering problems, including the optimization of CO2 capture processes (e.g., Rectisol and Selexol), Gas-Steam turbine Combined Cycles for special applications, and Organic Rankine Cycles.
