Bounding the Resource Availability of Activities with Linear Resource Impact
We introduce the Linear Resource Temporal Network (LRTN), which consists of activities that consume or produce a resource, subject to absolute and relative metric temporal constra...

On the Exponent of the All Pairs Shortest Path Problem
The upper bound on the exponent, ω, of matrix multiplication over a ring that was three in 1968 has decreased several times and since 1986 it has been 2.376. On the other hand, t...

Tree Canonization and Transitive Closure
We prove that tree isomorphism is not expressible in the language (FO + TC + COUNT). This is surprising since in the presence of ordering the language captures NL, whereas tree is...

Extreme Delay Sensitivity and the Worst-Case Switching Activity in VLSI Circuits
Abstract We observe that the switching activity at a circuit node, also called the transition density, can be extremely sensitive to the circuit internal delays. As a result, sligh...

Autocorrelation Coefficients and Correlation Immunity of Boolean Functions
Abstract. We apply autocorrelation and Walsh coefficients for the investigation of correlation immune and resilient Boolean functions. We prove new lower bound for the absolute ind...

Smaller Two-Qubit Circuits for Quantum Communication and Computation
We show how to implement an arbitrary two-qubit unitary operation using any of several quantum gate libraries with small a priori upper bounds on gate counts. In analogy to librar...

Performance Bounds for AF Multi-Hop Relaying over Nakagami Fading
Abstract—This paper presents a new upper bound on the endto-end signal-to-noise ratio (SNR) of channel-assisted amplifyand-forward (AF) multi-hop relay networks. The harmonic mea...

Efficiency Bounds for Adversary Constructions in Black-Box Reductions
Abstract. We establish a framework for bounding the efficiency of cryptographic reductions in terms of their security transfer. While efficiency bounds for the reductions have been...

Tight Bounds on the Round Complexity of Distributed 1-Solvable Tasks
A distributed task T is 1-solvable if there exists a protocol that solves it in the presence of (at most) one crash failure. A precise characterization of the 1-solvable tasks was...

Automatic Complexity Analysis
One way to analyse programs is to to derive expressions for their computational behaviour. A time bound function (or worst-case complexity) gives an upper bound for the computatio...
