We introduce a natural heuristic for approximating the treewidth of graphs. We prove that this heuristic gives a constant factor approximation for the treewidth of graphs with bounded asteroidal number. Using a di erent technique, we give a O(log k) approximation algorithm for the treewidth of arbit

In this paper we give, for all constants k, l, explicit algorithms that, given a graph Ε½ . Gs V,E with a tree-decomposition of G with treewidth at most l, decide Ε½ . whether the treewidth or pathwidth of G is at most k, and, if so, find a Ε½ . tree-decomposition or path-decomposition of G of width at
