Changelog
This changelog lists only the most important changes. Smaller (bug)fixes as well as non-mature features are not part of the changelog. The releases of major and minor versions contain an overview of changes since the last major/minor update.
Version 1.1.x
- long run average computation via value iteration
- LP based MDP model checking
- solvers can now expose requirements
- unbounded reachability and reachability rewards now correctly respect solver requirements
- sound (interval) value iteration
- Support for Multi-objective multi-dimensional reward bounded reachability properties for MDPs.
- Developers can now change environment variables (such as the solver precisions) locally.
Version 1.1.1
- c++ api changes: Building model takes BuilderOptions instead of extended list of Booleans, does not depend on settings anymore.
- storm-cli-utilities now contains cli related stuff, instead of storm-lib
- storm-pars: support for welldefinedness constraints in mdps.
- symbolic (MT/BDD) bisimulation
- Fixed issue related to variable names that can not be used in Exprtk.
- DRN parser improved
Version 1.1.0 (2017/8)
- Support for long-run average rewards on MDPs and Markov automata using a value-iteration based approach.
- Storm can now check MDPs and Markov Automata (i.e. MinMax equation systems) via Linear Programming.
- Parametric model checking is now handled in a separated library/executable called storm-pars.
- Wellformedness constraints on PMCs:
- include constraints from rewards
- are in smtlib2
- fixed
- computation of only constraints without doing model checking is now supported
- Fix for nested formulae
- JANI: Explicit engine supports custom model compositions.
- Support for parsing/building models given in the explicit input format of IMCA.
- Storm now overwrites files if asked to write files to a specific location.
- Changes in build process to accommodate for changes in carl. Also, more robust against issues with carl.
- USE_POPCNT removed in favor of FORCE_POPCNT. The popcnt instruction is used if available due to march=native, unless portable is set. Then, using FORCE_POPCNT enables the use of the SSE 4.2 instruction
Version 1.0.x
Version 1.0.1 (2017/4)
- Multi-objective model checking support now fully included
- Several improvements in parameter lifting
- Several improvements in JANI parsing
- Properties can contain model variables
- Support for rational numbers/functions in decision diagrams via sylvan
- Elimination-based solvers (exact solution) for models stored as decision diagrams
- Export of version and configuration to cmake
- Improved building process
Version 1.0.0 (2017/3)
