一般折痕图案的平折性在二十多年前就被认为是困难的。在本文中,我们证明了决定平面折叠仍然是NP完全的,即使是盒打褶,折痕形成一个子集的正方形网格与对角线。此外,我们提供了新的术语来隐式地表示平面折叠的全局层顺序,并提出了一个新的平面简化框架网格对齐的小工具。
Flat foldability of general crease patterns was first claimed to be hard for over twenty years. In this paper we prove that deciding flat foldability remains NP-complete even for box pleating, where creases form a subset of a square grid with diagonals. In addition, we provide new terminology to implicitly represent the global layer order of a flat folding, and present a new planar reduction framework for grid-aligned gadgets.
