    dct:description """
              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 different technique, we give a $O(\\log k)$ approximation algorithm for the treewidth of arbitrary graphs, where $k$ is the treewidth of the input graph.
