cds 39.1 13 * **Tight Packing of Connected Components** (Bachelor)
cds 40.1 14 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.

cds 24.1 19 Our layout algorithm already supports the placement of edge labels. However, there's still room for improvement...
cds 39.1 20 * **Layering Algorithms** (Bachelor, Master)
21 Implement an alternative algorithm for the layer assignment problem used in the layer-based approach to graph layout. The focus of the algorithm could the consideration of the number of edge crossings, a given aspect ratio, or overall compactness.
22 * **Node Placement With a Focus on Compactness** (Master)
23 Node placement algorithms often try to draw as many edges as straight lines as possible. However, that usually results in less compact diagrams. The focus of this topic would be to devise or adapt a node placement algorithm that tries to strike a balance between straightness and compactness.
24 * **Compound Graph Layout** (Master)
25 Design and implement new concepts for computing layer-based layouts of compound graphs. The main focus shall be on //maintainability//: ensuring that the implementation can be kept working over the years. The main area to be considered here is the crossing minimization phase.
26 * **Force Based Drawing with Port Constraints** (Master)
27 Develop methods for integrating port constraints in force-based drawing approaches. The resulting node placement shall be evaluated using an edge router such as [[libavoid>>url:http://www.adaptagrams.org/||shape="rect"]] on the model library of [[Ptolemy>>url:http://ptolemy.eecs.berkeley.edu/||shape="rect"]].
28 * **Combining Forces and Layers** (Master)**
29 **Design and implement a layout algorithm that combines the force-based and the layer-based approaches. The first three phases of the layer-based approach shall be replaced by a node distribution computed with a force-based approach.

cds 39.1 35 * **Comment Attachment** (Bachelor)
ssm 33.1 36 When computing a new layout for a diagram that contains comments (comparable to comments in source code), the comments often get placed far away of the nodes they refer to. This is because often the reference is not explicitly encoded in the original model. We have used a distance-based metric in the past to discover references automatically, but there are lots of ideas for improvement. This bachelor thesis would implement them, perhaps come up with additional ideas, and finally evaluate them in a thorough experiment.
cds 39.1 37 * **Control Flow Graph Exploration / Visualization** (Bachelor)
38 Use pragmatics concepts (automatic layout, focus & context) for exploring/visualizing control flow graphs and specific paths, eg. as computed by OTAWA WCET analysis tool, eg. using KLighD.
cds 41.1 39 * **Compound Graph Exploration** (Bachelor, Master)
40 A new graph exploration approach should be examined which is uses different zoom levels for different compound nodes. This tries to map the "Google Maps approach" of only showing the information of interest at any given zoom level to the field of graph exploration.
