“…Current approaches to vessel hull resistance optimization rely on a mix between human experience and DDMs [1], [14], [16], [17], [19], [21], [22], [31], [32]. As the first step, human experts define a specific parametrization, i.e., a rich yet synthetic quantitative descriptors of a set of candidate geometries, and parameter ranges, i.e., the geometry design space [1], [14], [16], [17], [19], [21], [22], [31], [32]. For this purpose, several approaches exist in the literature: from Free-Form Deformation (FFD) [1], [16], [17], [19], [21], [22] to B-Splines [14], [22], and model design parameters [31], [32] each one having its strengths and weaknesses (Section II).…”
