Distance Oracles for Sparse Graphs
Abstract— Thorup and Zwick, in their seminal work, introduced the approximate distance oracle, which is a data structure that answers distance queries in a graph. For any integer...

Bounded-depth circuits cannot sample good codes
We study a variant of the classical circuit-lower-bound problems: proving lower bounds for sampling distributions given random bits. We prove a lower bound of 1 - 1/n(1) on the st...

Fault Coverage Estimation for Early Stage of VLSI Design
This paper proposes a new fault coverage estimation model which can be used in the early stage of VLSI design. The fault coverage model is an exponentially decaying function with ...
