Abstract
The author built up a hierarchical parallel genetic compound form algorithm (H-P-G-C) which was develop based on delicate variables' segments, parallel algorithm, genetic algorithm (GA) and compound form algorithm. An optimizing model of navigation performances and structural properties for inland ships was constructed. This composite algorithm is programmed by VC++, it has a friendly graphical user interface. Quantities of computation results of comparison between different solving methods show that this composite algorithm has a solid foundation for form optimization and design evaluation of inland ships.
