This paper describes a class of novel initializations in Deterministic Particle Swarm Optimization (DPSO) for approximately solving costly unconstrained global optimization problems. The initializations are based on choosing specific dense initial po

Adaptive multi-fidelity metamodel for CFD-based optimization via radial basis functions and preliminary results on analytical benchmark problems

Autor: Riccardo Pellegrini, Andrea Serani, Cecilia Leotardi, Matteo Diez

The report presents a multi-fidelity metamodel to combine data produced by CFD computer simulations with different accuracy, such as potential ow and Reynolds averaged Navier-Stokes equations solvers. The multi-fidelity (MF) metamodel is based on sto

Global derivative-free deterministic algorithms are particularly suitable for simulation-based optimization, where often the existence of multiple local optima cannot be excluded a priori, the derivatives of the objective functions are not available,

The simulation-based design (SBD) process of complex engineering systems (such as ground, aerial, and marine vehicles) requires computationally expensive physic-based solvers, in order to achieve accurate solutions. Often, structural and/or computati
