New global optimization methods for ship design problems

Abstract: The aim of this paper is to solve optimal design problems for industrial\ud applications when the objective function value requires the evaluation of expensive\ud simulation codes and its first derivatives are not available. In order to achieve this goal\ud we propose two new algorithms that draw inspiration from two existing approaches:\ud a filled function based algorithm and a Particle Swarm Optimization method. In order\ud to test the efficiency of the two proposed algorithms, we perform a numerical compar… Show more

“…Such an approach can be too expensive (often almost unaffordable) in SBD optimization for industrial applications, when CPU-time expensive computer simulations are used directly as analysis tools. For this reason, deterministic approaches have been successfully developed and applied to SBD optimization, including hydrodynamic problems [5,11].…”

“…In particular, we refer to the generator of starting points DIRGEN [3], which is a DIRECT-type strategy [9]. Differently from the simple uniform random sampling, this choice allows to densely cover the search domain (see, e.g.…”

“…The probabilistic operating scenario is that shown in Table 1. For MRDO, a particle swarm optimization (PSO) algorithm (Campana et al 2009) is imposed over the UQ, whereas for deterministic MDO, the same algorithm is imposed over the MDA. For both approaches, a maximum number of 3,000 objective function evaluations is assumed.…”
