* **1 Tight Packing of Connected Components** (Bachelor, Master) |
| 30 |
30 |
Different connected components of a graph are often laid out separately and combined again afterwards. This combination step often produces too much whitespace. Research relevant 2D packing literature and implement a better solution. |

* **2 Heuristics for the Compact Layering Problem** (Bachelor, Master) |
| 40 |
40 |
Usually the layer assignment problem of the layer-based approach seeks to let as many edges as possible point into the same direction. Refraining from doing so sometimes allows more compact drawings, which so far has been evaluated using optimization problems. The task is to find and evaluate appropriate heuristics. |

+* **1 A (Simple) Edge Router** (Bachelor, Master) |
| 60 |
60 |
Often, people want their nodes to stay in the same place, but have the edges routed somehow. We currently don't have any layout algorithm that can do so. In this assignment, you would implement a simple edge router to solve this. |
