Evaluating a weighted graph polynomial for graphs of bounded tree-width
The electronic journal of combinatorics, Tome 16 (2009) no. 1
We show that for any $k$ there is a polynomial time algorithm to evaluate the weighted graph polynomial $U$ of any graph with tree-width at most $k$ at any point. For a graph with $n$ vertices, the algorithm requires $O(a_k n^{2k+3})$ arithmetical operations, where $a_k$ depends only on $k$.
