无形状的

And when it\'s vanished still declare, With only bed and bedstead there, That heavens had opened.

还有无云的天空，多像睡觉的人醒了又在梦中，看到的那些仿佛如此的形状这种形状消失了，只剩下床和床架，依然在声言天国的门打开了。

Considering minimization of total wire length as the objective, it allows virtual blocks to transform into rectilinear shapes without overlaps and selects the optimum shapes for virtual blocks. It is based on the dead space block assignment and pin allocation during the process of packing.

该算法以线长最小化为目标，通过在位置优化过程中对虚拟模块进行无重叠的直角多边形变形来实现虚拟模块的形状优化，形状优化过程是基于模块填装过程中的空白区分配算法和引脚分配算法，并以降低线网在半周长模式下的线长下限为其主要理论依据。
