OBDDimal

The goal of the project "Optimal Binary Decision Diagrams for Information Visualization, Model Analysis, and Logic Operations" (OBDDimal, for short) focuses at its core on improving the scalability of binary decision diagrams (BDDs) and related data structures. Domains which would benefit from an increase in scalability are, among others, information visualization (e.g., interactive configurators), model analysis (e.g., feature-model analysis, static code analysis), and logic operations in general (e.g., negation of CNFs).
