The width measuretreedepth, also known as vertex ranking, centered coloring and elimination tree height, is a well-established notion which has recently seen a resurgence of interest. We present an algorithm which—given as input ann-vertex graph, a tree decomposition of widthw, and an integert—decides whether the input graph has treedepth at mosttin time 2O(wt)·n. We use this to construct further algorithms which do not require a tree decomposition as part of their input: A simple algorithm which decides treedepth in linear time for a fixedt, thus answering an open question posed by Ossona de Mendez and Nešetřil as to whether such an algorithm exists, a fast algorithm with running timeand an algorithm for chordal graphs with running time 2O(tlogt)·n.
