The efficiency and precision of traditional particle swarm optimization were always influenced deeply by initial positions of particles and the initialization of random numbers, especially in the optimization of the best principal dimensions of ship. The numerical distributions of different chaotic sequences were analyzed in this paper, and the chaotic sequences were introduced into particle swarm...
The method of amending chord length parameterization was used to process different feasible point vectors of ship's section area, and the parameterized cubic spline curves were used to express the different subsections of ship's section area curve (SAC). The work of designing a good ship's SAC was converted to a problem of multi-objective optimization. The objects of single functions were set as the...
