> The basic idea of this algorithm is to evolve the generation of chromosome, where a chromosome is a cuboid set to prebuilt. The detailed steps are as follows:
> # Initialize a generation of chromosome
> # Evolve the generation by selection, crossover and mutation by N round.
> # From the final generation, choose a best chromosome that is a best cuboid set to recommend.
