چکیده

In the Intervalizing Colored Graphs problem, one must decide for a given graph G = (V,E) with a proper vertex coloring of G whether G is the subgraph of a properly colored interval graph. For the case that the number of colors k is xed, we give an exact algorithm that uses O∗(2n/log (n)) time for all > 0. We also give an O∗(2n) algorithm for the case that the number of colors k is not xed.

The hardness of intervalizing four colored caterpillars

The problem of Intervalizing Colored Graphs (ICG) has received a lot of attention due to their use as a model for DNA physical mapping with ambiguous data. If k is the number of colors, the problem is known to be NP-Complete for general graphs for k 4 and has polynomial time algorithms for k = 2 and k = 3. In this paper we show that the ICG problem is NP-complete when the graph is a caterpillar...

The hardness of perfect phylogeny, feasible register assignment and other problems on thin colored graphs

In this paper, we consider the complexity of a number of combinatorial problems; namely, Intervalizing Colored Graphs (DNA physical mapping), Trian-gulating Colored Graphs (perfect phylogeny), (Directed) (Modified) Colored Cutwidth, Feasible Register Assignment and Module Allocation for graphs of bounded pathwidth. Each of these problems has as a characteristic a uniform upper bound on the tree...

On Intervalizing K-colored Graphs for DNA Physical Mapping

The problem to determine whether a given k-colored graph is a subgraph of a properly colored interval graph has an application in DNA physical mapping. In this paper, we study the problem for the case that the number of colors k is xed. For k = 2, we give a simple linear time algorithm, for k = 3, we give an O(n) algorithm for biconnected graphs with n vertices, and for k = 4, we show that the ...
