DESCRIPTION:Prof. Emanuele Martelli\, Politecnico di Milano\nIn the areas 
 of chemical processes and energy systems\, the relevance of black-box opti
 mization problems is growing because they arise not only in the optimizati
 on of processes with modular/sequential simulation codes but also when dec
 omposing complex optimization problems into bilevel programs\, or when opt
 imizing. The objective function is typically discontinuous\, non-different
 iable\, not defined in some points\, noisy\, and subject to linear and non
 linear relaxable and unrelaxable constraints.\nDr. Martelli\, after briefl
 y reviewing the main available derivative-free methods applicable to this 
 class of problems\, will present PGS-COM\, the hybrid algorithm he recentl
 y developed with Prof. E. Amaldi\, and its applications in the area of pro
 cess engineering and energy systems. The algorithm combines the positive f
 eatures of the Particle Swarm Optimizer\, Generating Set Search\, and Comp
 lex.\nThe performance of PGS-COM has been benchmarked against eleven state
 -of-the-art derivative-free methods and tested on several process engineer
 ing problems\, including the optimization of CO2 capture processes (e.g.\,
  Rectisol and Selexol)\, Gas-Steam turbine Combined Cycles for special app
 lications\, and Organic Rankine Cycles.\nBio:\n2010: PhD degree in Energy
