Learning Monotone Decision Trees in Polynomial Time
We give an algorithm that learns any monotone Boolean function f : {-1, 1}n {-1, 1} to any constant accuracy, under the uniform distribution, in time polynomial in n and in the de...

Round-Efficient Broadcast Authentication Protocols for Fixed Topology Classes
Abstract--We consider resource-constrained broadcast authentication for n receivers in a static, known network topology. There are only two known broadcast authentication protocols...

Matching Polyhedral Terrains Using Overlays of Envelopes
For a collection F of d-variate piecewise linear functions of overall combinatorial complexity n, the lower envelope E(F) of F is the pointwise minimum of these functions. The min...

BackRank: an alternative for PageRank?
This paper proposes to extend a previous work, The Effect of the Back Button in a Random Walk: Application for PageRank [5]. We introduce an enhanced version of the PageRank algor...

A nearly optimal oracle for avoiding failed vertices and edges
We present an improved oracle for the distance sensitivity problem. The goal is to preprocess a directed graph G = (V, E) with non-negative edge weights to answer queries of the f...
