Quantum algorithmic randomness [PDF]

open access: yesJournal of Mathematical Physics, 2021
Quantum Martin-Löf randomness (q-MLR) for infinite qubit sequences was introduced by Nies and Scholz [J. Math. Phys. 60(9), 092201 (2019)]. We define a notion of quantum Solovay randomness, which is equivalent to q-MLR. The proof of this goes through a purely linear algebraic result about approximating density matrices by subspaces.

On Application of the Ray-Shooting Method for LQR via Static-Output-Feedback

open access: yesAlgorithms, 2018
In this article we suggest a randomized algorithm for the LQR (Linear Quadratic Regulator) optimal-control problem via static-output-feedback. The suggested algorithm is based on the recently introduced randomized optimization method called the Ray ...

Matching solid shapes in arbitrary dimension via random sampling [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We give simple probabilistic algorithms that approximately maximize the volume of overlap of two solid, i.e. full-dimensional, shapes under translations and rigid motions. The shapes are subsets of $ℝ^d$ where $d≥ 2$.

The Online Reservation Problem

open access: yesAlgorithms, 2020
Many sharing-economy platforms operate as follows. Owners list the availability of resources, prices, and contract-length limits. Customers propose contract start times and lengths. The owners decide immediately whether to accept or decline each proposal,

Model checking randomized distributed algorithms [PDF]

open access: yes, 2020
International audienceRandomization is a powerful paradigm to solve hard problems, especially in distributed computing. Proving the correctness, and assessing the performances, of randomized distributed algorithms, is a very challenging research ...

Novel and Efficient Randomized Algorithms for Feature Selection

open access: yesBig Data Mining and Analytics, 2020
Feature selection is a crucial problem in efficient machine learning, and it also greatly contributes to the explainability of machine-driven decisions. Methods, like decision trees and Least Absolute Shrinkage and Selection Operator (LASSO), can select ...

A Quantum Algorithm for the Commutativity of Finite Dimensional Algebras

open access: yesIEEE Access, 2019
A quantum procedure for testing the commutativity of a finite dimensional algebra is introduced. This algorithm, based on Grover's quantum search, is shown to provide a quadratic speed-up (when the number of queries to the algebra multiplication ...

Formalizing Randomized Matching Algorithms [PDF]

open access: yesLogical Methods in Computer Science, 2012
Using Je\v{r}\'abek 's framework for probabilistic reasoning, we formalize the correctness of two fundamental RNC^2 algorithms for bipartite perfect matching within the theory VPV for polytime reasoning.

Probabilistic Algorithmic Randomness

open access: yesThe Journal of Symbolic Logic, 2013
AbstractWe introduce martingales defined by probabilistic strategies, in which randomness is used to decide whether to bet. We show that different criteria for the success of computable probabilistic strategies can be used to characterize ML-randomness, computable randomness, and partial computable randomness.
