First,we have discovered stone artefacts in caves, which have similar features to that were broadly scattered in laterite terraces in Bose basin(0.8 Ma B.P),next study on deposits and fauna will be hopefully contributed to document paleoenvironmental background of early human;Second,early human fossils,Gigantopithecus and mammalian fossils unearthed in Mohui cave provide new evidence of early human origin; Third,after our scientific excavation in Fengshudao site in Bose basin, we have found five pieces of bi-face LCT with 10 tektites and nearly 100 stone artefacts form original laterite deposit.This important discovery is very answerable to international question about stratigraphic suspect of LCT; Fourth, abounding mammallian fossils with human fossils and remains from early Pleistocene to Holocene have been uncovered after systematically excavation in marginal cave of Bose basin.These discoveries are significant to the study on human evolution and establishment of sequence of Quarternary biological-stratigraphic in southern China.

According to this understanding, this thesis tries to modify PSO algorithm in order to improve its quality of solutions. The main approches include: using uniform design to ensure the uniform distribution of initial particles in the design space; adding mutation operation to increase the diversity of particles; decreasing the maximum velocity limitation and the velocity inertia automatically to balance the local and the global search efforts; developing a new approach to treat the design variables exceeding the bounds; using extensive local searches to escape local minimum. The overall effect of these approaches can yield better results for most test problems.
