| Abstract: | Collaborative Graphics Editing System(CGES)is an important research domain in computer supported cooperative work(CSCW).It allows multiple designers form different fields connected by communication networks synchronously or asynchronously to view or edit the same graphical object at the same time.The operational intention preservation and concurrent control is one of the important and complicated problems.The concurrent control strategy based on replicated structure is discussed.An effective concurrent control algorithm is presented to preserve the operational intention. |
