Incremental Recomputation of Recursive Queries with Nested Sets and Aggregate Functions
We examine the power of incremental evaluation systems that use an SQL-like language for maintaining recursively-de ned views. We show that recursive queries such as transitive clo...

Maintaining Connectivity in Dynamic Multimodal Network Models
Network data models are frequently used as a mechanism to describe the connectivity between spatial features in many emerging GIS applications (location-based services, transporta...

On Dynamic Shortest Paths Problems
We obtain the following results related to dynamic versions of the shortest-paths problem: (i) Reductions that show that the incremental and decremental singlesource shortest-paths...

ACG-Adjacent Constraint Graph for General Floorplans
ACG (Adjacent Constraint Graph) is invented as a general floorplan representation. It has advantages of both adjacency graph and constraint graph of a floorplan: edges in an ACG...

Performance of Scheduling Policies in Adversarial Networks with Non-synchronized Clocks
In this paper we generalize the Continuous Adversarial Queuing Theory (CAQT) model [5] by considering the possibility that the router clocks in the network are not synchronized. W...
