Faster Deterministic Streaming Vertex Coloring
Shiri Chechik, Hongyi Chen, Tianyi Zhang
Graph coloring is a fundamental problem in computer science. In the semi-streaming model, an input graph on vertices and maximum degree is presented as a stream of edg…
Simpler and Improved Replacement Path Coverings
Davide Bilò, Shiri Chechik, Keerti Choudhary +2
An important tool in the design of fault-tolerant graph data structures are -replacement path coverings (RPCs). An RPC is a family of subgraphs of a given grap…
Girth Approximations in the CONGEST Model
Shiri Chechik, Gur Lifshitz, Doron Mukhtar
This paper advances the state of the art in girth approximation within the CONGEST model. Manoharan and Ramachandran [PODC '24] provided the first significant improvement in girth…
Improved Streaming Edge Coloring
Shiri Chechik, Hongyi Chen, Tianyi Zhang
Given a graph, an edge coloring assigns colors to edges so that no pairs of adjacent edges share the same color. We are interested in edge coloring algorithms under the W-streaming…
Ãptimal Fault-Tolerant Labeling for Reachability and Approximate Distances in Directed Planar Graphs
Itai Boneh, Shiri Chechik, Shay Golan +2
We present a labeling scheme that assigns labels of size to the vertices of a directed weighted planar graph , such that for any fixed from the lab…
Improved Distance (Sensitivity) Oracles with Subquadratic Space
Davide Bilò, Shiri Chechik, Keerti Choudhary +3
A distance oracle (DO) with stretch for a graph is a data structure that, when queried with vertices and , returns a value such that $d(s,t…
