Each In atom is bonded with one Si atoms and two neighboring In atoms; b The adsorption energy of single In atom on the FHUC of the Si(111)-7x7 is 0.2eV higher than that on the UHUC. As a result, In atoms prefer to enucleate at the UHUC and develop into ordered dots array accordingly.

第一原理计算表明， a六个 In 原子在 Si(111)-7x7表面形成一种扭曲的六边形结构，每个 In 原子与一个衬底 Si 原子及两个相邻的 In 原子形成共价键，这些共价键具有类 sp2构型； b单个 In 原子吸附在 Si(111)-7x7单胞的 FHUC 时的吸附能较吸附在没有层错的一半的吸附能低0.2eV/原子，故而 In 团簇优先在 FHUC 成核生长并进而形成有序的点阵结构。

At the early iteratives, the mutation rate is bigger and the aim is to make particles to explore smaller and isolate region and to avoid the algorithm trapping to the local optimum. While the algorithm runs, the mutation rate will be decreased to reduce the disturbing to the particles. IPSO adopts a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space. Additionally, our algorithm incorporates a mechanism with a simple and easy penalty function based on the largest distance between the particle and the boundary of the feasible region to handle constraint.

IPSO采用了一种新型的变异策略，变异概率随着算法的运行是动态变化的：在算法运行初期，变异概率大，其目的是使算法不但能够探测到目标空间中的孤立区域，而且避免搜索陷入局部极值；在算法运行后期，变异概率逐渐变小，以减少对粒子的扰动；算法通过将部分具有邻近距离的粒子聚集成核形成多子群引导种群中粒子的飞行；采用一个简单的基于粒子与可行域边界最远距离的罚函数处理约束的机制，使得算法高效实现。
