https://doi.org/10.1057/9780230119666ve that for directed trees such embeddings do not always exist. Further, we investigate the related problem of upward simultaneous embedding without mapping, proving that deciding whether two directed graphs admit an upward simultaneous embedding without mapping is .-hard.

Algorithmic Meta Theoremstimisation problems on classes of graphs with excluded minors can be approximated in polynomial time to any given approximation ratio ..In my talk, I gave an overview of algorithmic meta theorems and the main techniques used in their proofs. Reference is a comprehensive survey of the material.

The Valve Location Problem in Simple Network Topologies (i) for series-parallel graphs and hence for graphs of treewidth two; (ii) if all edge weights equal one. If the network is a simple path, a cycle, or a tree, the problem can be solved in polynomial time. We also give a pseudo-polynomial time algorithm and a fully polynomial approximation scheme for networks of bounded treewidth.
