首先我对你做承诺。在学习完本贴之后，你可以手动对任何复杂的平面图进行四着色。
四色定理不再需要计算机，反过来，经过数学理论证明的四色定理可以用于密码学。
摘要：原创了“双螺旋统一化”，纯粹的数学算法，实现极大平面图的结构重组，并对点四 着色。算法复杂度为 O(n)。为四色定理的证明打下了理论基础。结构重组：在原有图结构 上根据四色定理的需求重新整合各种元素和制约条件，综合运用了分割、覆盖、等效转化等 方法，实现更高级的目标和意图，从而宏观的动态的解决四色定理。 关键词：四色定理；极大平面图；四着色；重组；螺旋；分割；覆盖
The Structural Reform of Maximal Planar Graph for The Four Color Theorem
Abstract: Original design of “Double Spiral Unification”, a pure mathematical algorithm that performs the structural reform of maximal planar graph and four-colors points. The complexity of the algorithm is O(n). It lays a theoretical foundation for the proof of the four-color theorem. The Structural Reform: based on the original structure of graph, according to the requirements of the four-color theorem to reintegrate various elements and constraints, to use the methods of segmentation, cover and equivalent transformation comprehensively, to achieve higher goals and intentions, so as to solve the four-color theorem dynamically from the macroscopic point of view. Keywords: four color theorem; maximal planar graph; four coloring; reform; spiral; segmentation; cover
