In prior work, we have revealed that CRDT is like OT in following the same general transformation approach and CRDT is not natively commutative for concurrent operations in co-editors, which helps to clarify ...
However, concurrency issues are inherent and unavoidable in unconstrained co-editing (and they are the same to both OT and CRDT), so CRDT solutions have to face and handle concurrency issues in content-specific ...

In this paper we aim to explore how students' understanding these abstractions by examining 137 solutions to two concurrency questions given on the final exam in two years of an introductory concurrency ...
One reason for this may be due to the fact that abstractions used in concurrent programs leave more situations undefined compared to sequential programs (e.g., in what order statements are executed), which ...
