简介：在这篇论文，为综合的一个有效系统任意的多角形的表面上的动物皮肤模式被开发。完成这项任务，同种细胞的马赛克(厘米)模型启发的一个系统被建议。厘米模型在任意的表面上模仿房间的反应。由控制部门，变化；房间的排斥，房间的调整空间安排被形成。细胞的这安排显示出呼吁的结果，它是可比较的，那些自然模式从动物皮肤观察了。然而，一个典型厘米模拟过程招致高计算的费用，在在越过多角形的表面的房间之中的距离被测量的地方；房间的运动在表面上被抑制。在这个框架，一条途径被建议转变每进它的正规参考面的表面的几何飞机组织的原来的3D。这结构帮助简化3D计算问题进一个更可管理的2D问题。而且，局部松弛的概念被开发最佳地为典型厘米模拟提高松弛过程。建议解答方法的表演与广泛的试验性的结果被验证了。

简介：Coalitional技巧比赛(CSG)是在每个代理人有被要求完成许多任务的一套技巧的不明确的环境的合作的一个简单模型，每项任务要求一套技巧被完成，但是每技巧是很难的被确定并且能仅仅是表示的品质上。因此远，包围CSG的许多计算问题被学习了。就我们的知识而言，作为CSG的一个中央问题，然而，联盟结构产生问题(CSGP)是极其挑战性的并且很好没被解决。到这个目的，二个不同计算智力算法此处被评估：二进制粒子群优化(BPSO)和二进制微分进化(BDE)。特别地，我们与二维的二进制代码编码开发二个随机的搜索算法并且相应为单个修理启发式。在那以后，我们讨论一些基本性质求婚启发式。最后，我们为在CSG解决CSGP把改进BPSO和BDE与最先进的算法作比较。试验性的结果证明我们的算法能与存在途径在最佳的答案附近发现一样，但是花极其短的时间，特别在大问题尺寸下面。
