Counting Triangles in Graph Streams with Repeatable and Forgettable Edges
Sourav Chakraborty, Debarshi Chanda, Arijit Ghosh +3
Most existing graph streaming algorithms assume the ideal scenario where each edge arrives only once. Real-world graph streams, such as communication or transaction logs, often con…

Computing over Data Streams using Catalytic Space
Ripley Becker, Sourav Chakraborty, Debarshi Chanda +2
We introduce a streaming model with \emph{catalytic memory}, an auxiliary workspace that must be returned to its initial state at the end of the computation. We show that catalytic…
