7	7	* **Add Support for Self Loops for Polyline / Spline Layouts
8		-**Self loops, that is, edges connecting a node with itself, need to be properly routed. This is already implemented for orthogonal edge routing, but is still an open problem for spline and polyline edge routing. (See ticket [[KIELER-2136>>url:http://rtsys.informatik.uni-kiel.de/jira/browse/KIELER-2136||shape="rect"]].)
9		-* **Heuristics for Side Aware Edge Label Placement**
10		-Think about and implement heuristic algorithms for solving the edge aware edge label placement problem for placing edge labels in data flow diagrams.
11		-* **Implement Greedy Switch Heuristic for Crossing Minimization**
12		-The order of nodes in a layer determines the number of crossings and is computed during the crossing minimization step. The results can usually be further improved by switching the order of nodes around, which we currently lack proper algorithms for. (See ticket [[KIELER-1871>>url:http://rtsys.informatik.uni-kiel.de/jira/browse/KIELER-1871||shape="rect"]])

15		-**Node Placement Algorithms**
16		-Implement alternative algorithms for node placement to minimize the number of bend points produced.
	13	+* **Integrate KIML with JGraph**
	14	+Provide automatic layout through KIML for the JGraph diagram library and develop a simple JGraph-based graph editor to test the integration with.

20	20	* **Control Flow Graph Exploration / Visualization**
21	21	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.
22		-* **Incremental Update for Klighd**
23		-Incremental update of Klighd data structure after editing.
24	24	* **OMG DD Format**
25	25	Explore the mapping of [[KGraph>>doc:KGraph Meta Model]] / [[KRendering>>doc:The KRendering Notation Model]] to the [[Diagram Definition>>url:http://www.omg.org/spec/DD/||shape="rect"]] format of the OMG.
26		-* **SyncCharts and Actor Model Visualization**
27		-Develop an integrated viewer for [[doc:SyncCharts]] and [[KAOM>>doc:Actor Oriented Modeling (KAOM)]] models using [[KLighD>>doc:Lightweight Diagrams (KLighD)]], including view management techniques such as focus & context and structure-based editing.
28		-* **Visualizing Model Edits/Changes**
29		-Develop and implement methods to visualize a model while it is edited. A particular concern here is the preservation of the mental map.
