Pseudorandom Generators, Measure Theory, and Natural Proofs
We prove that if strong pseudorandom number generators exist, then the class of languages that have polynomialsized circuits (P/poly) is not measurable within exponential time, in...

Reconstructing Strings from Substrings in Rounds
We establish a variety of combinatorial bounds on the tradeo s inherent in reconstructing strings using few rounds of a given number of substring queries per round. These results ...

Disjoint Paths in Densely Embedded Graphs
We consider the following maximum disjoint paths problem (mdpp). We are given a large network, and pairs of nodes that wish to communicate over paths through the network — the g...

An Approximation Scheme for Planar Graph TSP
We consider the special case of the traveling salesman problem TSP in which the distance metric is the shortest-path metric of a planar unweighted graph. We present a polynomial...
