In this article, we propose new heuristics for minimizing the amount of XOR gates required to compute a system of linear equations in GF(2). We first revisit the well known Boyar-Peralta strategy and ...
The QARMA Block Cipher Family -- Almost MDS Matrices Over Rings With Zero Divisors, Nearly Symmetric Even-Mansour Constructions With Non-Involutory Central Rounds, and Search Heuristics for Low-Latency S-Boxes
Tweakable Block Ciphers Almost MDS Matrices Even-Mansour Schemes
2016/5/9
We introduce and analyse a family of Almost MDS matrices defined over a ring with zero divisors that allows us to encode rotations in its operation while maintaining the minimal latency associated to ...
Branching Heuristics in Differential Collision Search with Applications to SHA-512
hash functions cryptanalysis SHA-512
2016/1/23
In this work, we present practical semi-free-start collisions for SHA-512 on up to 38 (out of 80) steps with complexity 240.5 . The best previously published result was on 24 steps. The attack is b...
Fluid Heuristics, Lyapunov Bounds, and Efficient Importance Sampling for a Heavy-tailed G/G/1 Queue
State-dependent importance sampling Rare-event simulation Heavy-tails
2015/7/6
We develop a strongly efficient rare-event simulation algorithm for computing the tail of the steady-state waiting time in a single server queue with regularly varying service times. Our algorithm is ...
Scheduling Heuristics for Maximizing the Output Quality of IRIS Task Graphs in Multiprocessor Environment with Time and Energy Bounds
precedence constraints computational load cost functions reward service dynamic voltage scaling
2014/12/8
Embedded real time applications are often subject to time and energy constraints. Real time applications are usually characterized by logically separable set of tasks with precedence constraints. The ...

Background: Many of the reproductive decisions that humans make happen without much planning or forethought, arising instead through the use of simple choice rules or heuristics that involve relativel...
Heuristics on pairing-friendly elliptic curves
Elliptic curves finite fields pairing-based cryptography
2011/8/23
Abstract: We present a heuristic asymptotic formula as $x\to \infty$ for the number of pairing-friendly elliptic curves with fixed embedding degree $k\geq 3$, with fixed discriminant, with rho-value b...
Noncommutative field theories are a class of theories beyond the standard model of elementary particle physics. Their importance may be summarized in two facts.Firstly as field theories on noncommutat...

From constructive field theory to fractional stochastic calculus. (I) An introduction: rough path theory and perturbative heuristics
fractional Brownian motion stochastic integrals rough paths
2011/2/22
Let B = (B1(t), . . . ,Bd(t)) be a d-dimensional fractional Brownian motion with Hurst index ≤ 1/4, or more generally a Gaussian process whose paths have the same local regularity. Defining properly...
A survey of the Poincaré Center Problem in degree 3 using finite field heuristics
survey Poincaré Center Problem degree 3
2011/2/21
We compare a heuristic count of components of the center variety in degree 3 with the equivalent count obtained from known families.From this comparison we conjecture that more than 100 unknown compon...
Traffic Independent Heuristics for Regenerator Site Selection for Providing Any-to-Any Optical Connectivity
Networks Optical communications
2015/6/9
We study single path-based heuristics with ranking and redirection, and connectivity dependent heuristics based on k-center and connected dominating set problems, for regenerator site selection to pro...
Cooperation and Friendship Choice Heuristics in Dynamic Local Interaction Networks
Cooperation and Friendship Choice Dynamic Local Interaction Networks
2009/11/30
I built an agent-based model that simulates economic interaction in a social
network. In the model, agents dynamically break and create network links
based on whether their neighbors cooperate in ...
The Socio-Cultural Dimension of Academic Literacy Development and the Explicit Teaching of Genres as Community Heuristics
Socio-Cultural Dimension Academic Literacy Development
2009/8/18
In this article I argue that literacy classes in post-secondary institutions can play a pivotal role in the development of Generation 1.5 students’ academic literacy and, consequently, their ability t...
Heuristics and representational change in two-move matchstick arithmetic tasks
insight heuristics representational change
2009/4/28
Insight problems are problems where the problem solver struggles to find a solution until * aha! * the solution suddenly appears. Two contemporary theories suggest that insight problems are difficult ...
