25	25	//» Dienste.// Algorithmen und Meta Layout müssen den Anwendern zugänglich gemacht werden, damit ein Nutzen daraus entsteht. Dazu müssen wir verschiedenste graphische Frameworks mit vorhandenen Layout-Bibliotheken integrieren und eine Reihe von Werkzeugen entwickeln, mit denen die Verfügbarkeit unserer Lösungen gesteigert wird. Hierzu gehört z.B. die Unterstützung von Standard-Graphenformaten sowie ein Web-Service für automatisches Layout.

	27	+* **1 Tight Packing of Connected Components** (Bachelor, Master)
28	28	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.

37		-* **Layering Algorithms** (Bachelor, Master)
	37	+* **2 Layering Algorithms** (Bachelor, Master)
38	38	Implement an alternative algorithm for the layer assignment problem used in the layer-based approach to graph layout. The focus of the algorithm could be the consideration of the number of edge crossings, a given aspect ratio, or overall compactness.
39		-* **Node Placement With a Focus on Compactness** (Master)
	39	+* **2 Node Placement With a Focus on Compactness** (Master)
40	40	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.

44		-* **Force Based Drawing with Port Constraints** (Master)
	44	+* **3 Force Based Drawing with Port Constraints** (Master)
45	45	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"]].
46		-* **Combining Forces and Layers** (Master)**
	46	+* **3 Combining Forces and Layers** (Master)**
47	47	**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.
48		-* **Interactive constraint creation and application in automatic layout **(Bachelor/Master)
49		-Evaluate options how to create constraints on the layout like "Node x should be placed at position y" and how to implement this in the current layout algorithms.
	48	+* **2 Interactive Constraint Creation and Application in Automatic Layout **(Bachelor/Master)
	49	+Evaluate options how to create constraints on the layout like "Node x should be placed at position y" and how to implement this in the current layout algorithms. Assess how such constraints can be persisted within the model.

53		-* **Orthogonal "Edge Bundling"** (Bachelor, Master)
54		-Implement and evaluate strategies for orthogonal edge bundling within our layer-based layout algorithm.
55		-* **A Simple Edge Router** (Bachelor)
	53	+* **1 A Simple Edge Router** (Bachelor)
56	56	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.
57		-* **Improved Spline Edge Routing **(Master)
	55	+* **1 Improved Spline Edge Routing **(Master)
58	58	Our layer-based layout algorithm is capable to route edges as splines. Evaluate the results using state machine diagrams, identify possible improvements and develop solutions to address these.
59		-* **Improve and Assess KLay Layered's JUnit Test Environment **(Bachelor, Master)
	57	+* **1 Improve and Assess KLay Layered's JUnit Test Environment **(Bachelor, Master)
60	60	We maintain a variety of JUnit tests to assure our layout algorithm works properly. The environment to execute these tests grew over time and requires a face-lift. The task is to evaluate existing testing frameworks of other projects, find a clean and efficient way to specify and maintain our tests, and update the current implementation.
