The average desired velocity of the drivers has been assumed to be proportional to the instantaneous velocity by M ndez and Velasco when a alternative model was proposed. Based on this postulate, the desired velocity of a single driver delineates to be proportional to the local instantaneous velocity in this paper, which is a property of aggressive drivers who all want to drive with the maximum velocity. However, the deriver does not occupy this aggressive characteristic all the time.

基于M ndez 和Velasc关于司机平均期望速度与瞬时速度成比例的假设，认为个体司机的期望速度与其局域瞬时速度成比例，期望以更大的速度行驶，然而并非所有的司机都具有这样的进取特性，为了抑制司机这样的进取特性，引入适应性公式来近似表达单个司机期望速度随时间的变化率。

In addition, the maximum velocity in larvae was significant higher than those in pupae and adults. In vitro inhibition studies of larvae AChE indicated that the I50 values of 20-d larvae were higher than those of 10-d larvae when treated with eserine, malaoxon and carbaryl, respectively, suggesting that AChE in 20-d larvae was less sensitive to the inhibitors.

通过对幼虫AChE离体抑制作用测定表明，毒扁豆碱、马拉氧磷和西维因对20d龄幼虫的抑制中浓度I50均高于10d龄幼虫，说明20d龄幼虫体内的AChE对3种抑制剂的抑制作用更不敏感。

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.

有鉴於此，本文针对粒子群演化法之流程参考相关文献并稍作改变，使得粒子群演算法在结果的收敛上更具优势，本文的主要改进的方法包括：应用均匀设计的概念使得初始的粒子可以更均匀地分布在空间上；利用突变增加粒子之间的差异性与多样性；利用适当控制的最大速度限制及惯性权重控制，达到区域搜寻与全域搜寻的效果；应用新的边界处理机制处理设计变数超过上、下限的问题；利用区域强化搜寻针对粒子附近地区，再作进一步的搜索以得到更佳之结果；将各种方法综合后配合粒子群演算法使用，可以得到不错的结果。
