AI总结:
本文研究了装配图中最大哈密顿路径集合数的条件及特殊结构,证明最大值仅在特定类型装配图中实现。
摘要:
我们为简单装配图(所有顶点度数为1或4的刚性顶点图)提供了四个等价的组合条件,以确定其相对于大小的最大哈密顿路径集合数。这些条件用于证明猜想:最大值等于$F_{2n+1}-1$,其中$F_k$表示第k个斐波那契数,仅在特定的装配图中实现,称为纠缠弦。
英文摘要:
We provide four equivalent combinatorial conditions for a simple assembly graph (rigid vertex graph where all vertices are of degree 1 or 4) to have the largest number of Hamiltonian sets of polygonal paths relative its size. These conditions serve to prove the conjecture that such maximum, which is equal to $F_{2n+1}-1$, where $F_k$ denotes the $k$th Fibonacci number, is achieved only for special assembly graphs, called tangled cords.
