Center node: "extending partial representations of circle graphs"
  Abstract: The partial representation extension problem is a recently introduced generalization of the recognition problem. A circle graph is an intersection graph of chords of a circle. We study the partial representation extension problem for circle graphs, where the input consists of a graph $G$ and a partial representation $\cal R'$ giving some pre-drawn chords that represent an induced subgraph of $G$. The question is whether one can extend $\cal R'$ to a representation $\cal R$ of the entire graph $G$, i.e., whether one can draw the remaining chords into a partially pre-drawn representation to obtain a representation of $G$. Our main result is an $O(n^3)$ time algorithm for partial representation extension of circle graphs, where $n$ is the number of vertices. To show this, we describe the structure of all representations of a circle graph using split decomposition. This can be of independent interest.
