,Simultaneous Drawing of?Layered Trees, describe a dynamic program running in polynomial time for the restricted case of two trees. If there are more than two trees, we restrict the number of layers to three, which allows for a reduction to a shortest-path problem. This way, we achieve XP-time in the number of trees.

,The Parameterized Complexity of?Terminal Monitoring Set,od diversity, and feedback edge number. For the weighted version of the problem, we obtain a FPT algorithm with respect to vertex cover number, and for a relaxed version of the problem, we show that it is W[1]-hard with respect to solution size plus feedback vertex number.

For example, 000,?001,?010,?100 is a no instance of the first question, while 1234,?1324,?1243 is a yes instance of the second question due to the order .. We prove that a variety of Gray coding problems are NP-complete using a new tool we call a ..
