We study the mixed-integer rounding (MIR) closures of polyhedral sets. The MIR closure of a polyhedral set is equal to its split closure and the associated separation problem is N...
We establish the first nontrivial lower bounds on timespace tradeoffs for the selection problem. We prove that any comparison-based randomized algorithm for finding the median ...
This paper presents an embedded security sublanguage for enforcing informationflow policies in the standard Haskell programming language. The sublanguage provides useful informat...
Oblivious transfer is a fundamental primitive in cryptography. While perfect information theoretic security is impossible, quantum oblivious transfer protocols can limit the disho...
Pointer analysis statically approximates the heap pointer structure during a program execution in order to track heap objects or to establish alias relations between references, a...
