We consider the #P-complete problem of counting the number of linear extensions of a poset (LE is fixed-parameter intractable parameterized by the treewidth of the cover graph. This resolves an open problem recently posed in the Dagstuhl seminar on Exact Algorithms. On the positive side we show thatPeer reviewe
