我们证明了在多次计数(“弱简约”)约简下,四次4顶点连通平面图上的哈密顿环计数是完全的,并且对于这个整数计数问题不存在完全多项式时间随机化近似方案(FPRAS),除非。
We show that counting Hamiltonian cycles on quartic 4-vertex-connected planar graphs is-complete under many-one counting (“weakly parsimonious”) reductions, and that no Fully Polynomial-time Randomized Approximation Scheme (FPRAS) can exist for this integer counting problem unless.
