摘要 匹配计数问题是一个著名的难问题,考虑它的两个参数化问题p-deg-#MATCHING与p-#MATCHING,证明了p-deg-#MATCHING是固定参数易解的,p-#MATCHING有固定参数易解随机近似方案。 Counting matching problem is an intractable problem.Considering its corresponding parameterized problems p-deg-#MATCHING and p-#MATCHING,p-deg-#MATCHING is proved to be fixed-parameter tractable and p-#MATCHING has a randomized approximation scheme of fixed-parameter tractable.
