We develop practically efficient algorithms for computing the treewidthof a graphG. The core of our approach is a new dynamic programming algorithm which, given a graphG, a positive integerk, and a setof minimal separators ofG, decides ifGhas a tree-decomposition of width at mostkof a certain canonical form that uses minimal separators only from, in the sense that the intersection of every pair of adjacent bags belongs to. This algorithm is used to show a lower bound ofon, settingto be the set of all minimal separators of cardinality at mostkand to show an upper bound ofkon, settingto be some, hopefully rich, set of such minimal separators. Combining this algorithm with new algorithms for exact and heuristic listing of minimal separators, we obtain exact algorithms for treewidth which overwhelmingly outperform previously implemented algorithms.
