On the proper intervalization of colored caterpillar trees
This paper studies the computational complexity of the problem (), when the input graph is a colored caterpillar, parameterized by hair length. In order prove our result we establish a close relationship between the and a graph layout problem the (). We show a dichotomy: the and the are NP-complete for colored caterpillars of hair length 2, while both problems are in P for colored caterpillars of hair length 2. For the hardness results we provide a reduction from the , while the polynomial...
