Testing Small Set Expansion in General Graphs
Angsheng Li, Pan Peng
We consider the problem of testing small set expansion for general graphs. A graph is a -expander if every subset of volume at most has conductance at least . Sma…

Detecting and Characterizing Small Dense Bipartite-like Subgraphs by the Bipartiteness Ratio Measure
Angsheng Li, Pan Peng
We study the problem of finding and characterizing subgraphs with small \textit{bipartiteness ratio}. We give a bicriteria approximation algorithm \verb|SwpDB| such that if there e…
