Journal of Combinatorial Theory, Series A, 2013 We present an algorithm to generate positive braids of a given length as words in Artin generators with a uniform probability. The complexity of this algorithm is polynomial in the number of strands and in the length of the generated braids. As a byproduct, we describe a finite state automaton accepting the language of lexicographically minimal ...

Generalized random forests [PDF]
The Annals of Statistics, 2019 We propose generalized random forests, a method for non-parametric statistical estimation based on random forests (Breiman, 2001) that can be used to fit any quantity of interest identified as the solution to a set of local moment equations. Following the literature on local maximum likelihood estimation, our method considers a weighted set of nearby ...

CoRR, 2021 In this article, we provide three generators of propositional formulae for arbitrary languages, which uniformly sample three different formulae spaces. They take the same three parameters as input, namely, a desired depth, a set of atomics and a set of logical constants (with specified arities). The first generator returns formulae of exactly the given

Mvgen: Multi Version Question Generation for Math Courses
Open Education Studies, 2019 A question generating system developed in Perl that uses LaTeX as typographical language is presented, which, besides random generation of different question types, allows a random creation of a large number of different test versions.

Random generation of Boolean functions with high degree of correlation immunity
Journal of Telecommunications and Information Technology, 2006 In recent years a cryptographic community is paying a lot of attention to the constructions of so called resilient functions for use mainly in stream cipher systems. Very little work however has been devoted to random generation of such functions.

Using Daphnia bio-sensor for random number generation [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2013 One of the most used bioassays for toxicity screening of chemicals and for toxicity monitoring of effluents and contaminated waters is the acute toxicity test performed with Daphnia Magna. Standard methods have been developed and gradually improved by

Fabrication-Friendly Random Meta-Atom Generation for Phase-Shifting Metasurfaces
IEEE Photonics Journal, 2022 Compared with traditional phase-shifting metasurface design methods, computer-aided optimization has attracted significant interest due to its advantages of high efficiency and a wide modulation range, resulting in the ability to generate various random ...

General Partitioning on Random Graphs [PDF]
Journal of Algorithms, 2002 Summary: Consider the General Partitioning (GP) problem defined as follows: Partition the vertices of a graph into \(k\) parts \(W_1,\dots, W_k\) satisfying a polynomial time verifiable property. In particular, consider properties specified by a pattern of requirements as to which \(W_i\) forms a sparse or dense subgraph and which pairs \(W_i\), \(W_j\)

Fast Generation of Discrete Random Variables
Journal of Statistical Software, 2004 We describe two methods and provide C programs for generating discrete random variables with functions that are simple and fast, averaging ten times as fast as published methods and more than five times as fast as the fastest of those. We provide general
