In this release, we supported process level fairness and improve the performance and fix bugs. The parameterized verification (handling infinite number of threads) is under implementation now. We will release a new version soon once we have tested the programs.
Process level Fairness
Process level week and strong fairness is supported in PAT.
1 Strong Fairness Checking performance improvement
2 Refinement Checking speed-up.
3 Use Static variables
4 Fair-Loop checking is improved for the non-buchi-fair loops.
User Interface Simplification
1 Remove the tree data manager since the memory saving is not significant and memory is cheap now.
2 Fairness options are grouped into a combobox. The options are dynamically changed according to the applicablity.
1 Leader Election Protocols
2 Web Service: Travel Agent
3 Linearizability: SNZI Algorithms
Parser Library is updated to ANTLR 3.1.2
