D32 Scalability
From Event-B
Overview
Regarding scalability of the Rodin platform, the following contributions has been made:
- (Alexei) Flow plug-in
- (Alexei) Group Refinement
- (Alexei) Modes
- Emre Yilmaz and Thai Son Hoang (ETH Zurich) has developed a plug-in for supporting an extension of Event-B with qualitative reasoning. The extension allows developer to declare an event converges probabilistically (with probability 1). This is in contrast with standard certain termination, where convergent events must decrease the declared variant. Providing that the variant is bounded above, an event probabilistically converges if it might decrease the variant.
