简介：在粒子从范围使变形到立方体包装密度的变化被学习。一个新模型被介绍描述在不同粒子形状之间的粒子变丑。变丑被部件范围的相对运动在一个粒子的范围集会模型模仿。在到立方体的变丑形式范围的粒子的随机的靠近的包装与一个改进松驰算法被模仿。在2D和3D盒子的包装被模仿。与模拟，当粒子球状在变丑减少时，我们发现收拾行李的密度增加。范围和立方体给最小(0.6404)和分别地在变丑包装密度的最大值(0.7755)。在每使变形的步，包装从一种随机的配置并且从最后一使变形的步的最后的收拾行李开始是模仿的两个。在后者盒子中的收拾行李的密度比在二种尺寸的前者大，但是在三种尺寸是更小的。变丑模型能也被用于另外的粒子形状。
