General information

DecoVis is a tool for analysing and visualizing dynamic programming (DP) on tree decompositions. An emphasis is on BDD (Binary Decision Diagram) based DP as implemented in dynBDD, for details see this paper.

DecoVis allows one to visualize the whole solving process, from input instance, over the tree decomposition to computations (BDDs). It provides tools for inspecting the relations between input, TD and computation as well as advanced statistic features and animations of the solving process.

The tool was developed in course of the Master's thesis "Designing a System for the Experimental Analysis and Visualization of Dynamic Programming on Tree Decompositions" by Thomas Ambroz and Andreas Jusits. Details about the system can be found here.

Web interface

DecoVis with preconfigured projects is available here:

Note that this online version only provides "view" support for existing data. To analyze your own DP algorithm executions, please download the full version provided below.
