Uppaal is an integrated tool environment for modeling, validation and verification of real-time systems modeled as networks of timed automata, extended with data types (bounded integers, arrays, etc.).

Uppaal Stratego [DJLMT15] facilitates generation, optimization, comparison as well as consequence and performance exploration of strategies for stochastic priced timed games in a user-friendly manner. The tool allows for efficient and flexible “strategy-space” exploration before adaptation in a final implementation by maintaining strategies as first class objects in the model-checking query language.

Uppaal Stratego {doi} generalizes techniques developed in the following tools and papers:

Like Uppaal, Uppaal Stratego is free for non-profit use, e.g. for evaluation, research, and teaching purposes. For more details please read the license.
