Pso is simple and efficient, so many researchers have been attracted by this algorithm, and furthermore, it converges fast by moving each particle aimed at guides when it deals with single - objective optimization, and these features are important in multi - objective optimization also. from some current research works, we describe a multi - objective particle swarm optimization algorithm ( mopso ) that incorporates the concept of the enhanced - dominance, we present this new concept to update the archive, the archiving technique can help us to maintain a sequence of well - spread solutions. a new particle update strategy and the mutation operator are shown to speed up convergence
目前，國內外已有部分相關研究成果，但是它們在解集分佈性、收斂性方面仍存在不足，在吸取已有成果的基礎上，本文提出了一種改進的多目標粒子群演算法（ mopso ） ，使用我們提出的強支配概念構造外部種群，使解集保持良好的分佈性，同時，通過採用新的全局極值和個體極值的選取方式及採用新的種群更新策略加快解集的收斂，提出基於快速排序的非支配集構造方法加快演算法運行效率。 -
For a quantized subgroup of the symmetry group of hamiltonian of a molecule, a site projection operator is defined to produce symmetry - adapted wave functions from the functions with the symmetry of the subgroup. based on site projection operator, a systematic method is proposed to factorize the single - particle
對于哈密頓的對稱群的量子化子群，可以定義一個位置投影運算元，來從具有該子群對稱性的軌道產生完全的對稱性匹配軌道。基於位置投影運算元，提出了一個系統的方法，用來按照分子的最大對稱群，徹底地分解
