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…
Algorithms and Hardness for Estimating Statistical Similarity
Arnab Bhattacharyya, Sutanu Gayen, Kuldeep S. Meel +3
We introduce and study the computational problem of determining statistical similarity between probability distributions. For distributions and over a finite sample space,…
Computational Explorations of Total Variation Distance
Arnab Bhattacharyya, Sutanu Gayen, Kuldeep S. Meel +3
We investigate some previously unexplored (or underexplored) computational aspects of total variation (TV) distance. First, we give a simple deterministic polynomial-time algorithm…
