%X s t -orientations ( s t -numberings) or bipolar orientations of undirected graphs are central to many graph algorithms and applications. Several algorithms have been proposed in the past to compute an s t -orientation of a biconnected graph. In this paper, we present new algorithms that compute such orientations with certain (parameterized) characteristics in the final s t -oriented graph, such as the length of the longest path. This work has many applications, including Graph Drawing and Network Routing, where the length of the longest path is vital in deciding certain features of the final solution. This work applies to other difficult problems as well, such as graph coloring and of course longest path. We present extended theoretical and experimental results which show that our technique is efficient and performs well in practice.
