5		-== Diagram Layout ==
6		-
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"]])
13		-* **Layering Algorithms**
14		-Implement an alternative algorithm for the layer assignment problem used in the layer-based approach to graph layout.

16		-== Modeling Pragmatics ==
17		-
18		-* **Control Flow Graph Exploration / Visualization**
19		-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.
20		-* **Incremental Update for Klighd**
21		-Incremental update of Klighd data structure after editing.
22		-* **OMG DD Format**
23		-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.
24		-* **SyncCharts and Actor Model Visualization**
	5	+* **Control flow graph layout**
	6	+Connect the KIELER layout algorithms to an external tool for control flow graphs used in compiler development.
	7	+* **SyncCharts and actor model visualization**
25	25	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.
26		-* **Visualizing Model Edits/Changes**
27		-Develop and implement methods to visualize a model while it is edited. A particular concern here is the preservation of the mental map.
28		-
29		-== Semantics and Synchronous Languages ==
30		-
31		-* **Validation Manager for Models**
32		-Develop an integrated, flexible and generic syntactic validation framework for models (e.g. Esterel or SyncCharts).
33		-* **Esterel / SyncCharts Validation**
34		-Automate the validation for a (generic) SyncCharts simulator employing the Esterel simulator and the Esterel to SyncCharts transformation.
35		-* **Transformation from SyncCharts to Esterel** [possibly also Master Topic]
	9	+* **Validation manager for models**
	10	+Develop an integrated, flexible and generic validation framework for models (e.g. Esterel or SyncCharts).
	11	+* **Railway track layout**
	12	+Use KLighD to visualize railway tracks.
	13	+* **Transformation from SyncCharts to Esterel**
36	36	Develop a transformation in Xtend2 to generate Esterel code for SyncCharts.
	15	+* **Instruments for data visualization**
	16	+Develop visualizations of data values (e.g. through charts) and integrate them in the KIELER environment.
	17	+* **Multicore Layout**
	18	+Find good ways of distributing layout tasks in hierarchical diagrams to the different cores of multicore CPUs. Also, evaluate when a multithreaded approach starts to make sense, and how best to implement it.

38		-== Miscellaneous Topics ==
39		-
40		-* **Developing an Info Screen**
41		-Info screens are screens that present data in ways that can be easily understood. This includes static data (project description graphics, members of a team, ...) as well as dynamically aggregated data (bug statistics, automatic build overviews, ...). This topic is about developing such an info screen for our group and making it easily configurable.

45		-* **SyncCharts in Yakindu**
46		-Develop a SyncChart-Editor based on Yakindu, including basic pragmatics concept (automatic layout, collapse/expand, structure-based editing) and interfacing to host-language.
	22	+* **Expression language and modularization**
	23	+Develop an expression language with a type system for SyncCharts. Implement modularization of SyncCharts models.
47	47	* **FPGA Statecharts**
48	48	Development of a Statecharts editor, based on .NET, WPF, MS Silverlight. Synthesis onto FPGAs with a data-flow-based intermediate format.
49		-* **Diagram Description Language**
50		-Developing the concepts and implementation of a diagram description language based on Klighd, with SyncCharts as application example.
51		-* **[Quartz]**
	26	+* **Quartz**
52	52	Integrate the synchronous Quartz language into KIELER for validation purposes and teaching.
	28	+* **Esterel / SyncCharts Validation**
	29	+Automate the validation for a (generic) SyncCharts simulator employing the Esterel simulator and the Esterel to SyncCharts transformation.
