A Survey of Machine Learning Assisted Continuous-Variable Quantum Key Distribution

open access: yesInformation, 2023
Continuous-variable quantum key distribution (CV-QKD) shows potential for the rapid development of an information-theoretic secure global communication network; however, the complexities of CV-QKD implementation remain a restrictive factor.

A factor graph based genetic algorithm

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2014
We propose a new linkage learning genetic algorithm called the Factor Graph based Genetic Algorithm (FGGA). In the FGGA, a factor graph is used to encode the underlying dependencies between variables of the problem.

Distributed Phase Estimation Algorithm and Distributed Shor's Algorithm

open access: yes, 2023
Shor's algorithm is one of the most significant quantum algorithms. Shor's algorithm can factor large integers with a certain success probability in polynomial time. However, Shor's algorithm requires an unbearable amount of qubits in the NISQ (Noisy Intermediate-scale Quantum) era.

Symmetric-Approximation Energy-Based Estimation of Distribution (SEED): A Continuous Optimization Algorithm

open access: yesIEEE Access, 2019
Estimation of Distribution Algorithms (EDAs) maintain and iteratively update a probabilistic model to tackle optimization problems. The Boltzmann Probability Distribution Function (Boltzmann-PDF) provides advantages when used in energy based EDAs ...

Interactions and Dependencies in Estimation of Distribution Algorithms

open access: yes2005 IEEE Congress on Evolutionary Computation, 2005
In this paper, we investigate two issues related to probabilistic modeling in Estimation of Distribution Algorithms (EDAs). First, we analyze the effect of selection in the arousal of probability dependencies in EDAs for random functions. We show that, for these functions, independence relationships not represented by the function structure are likely ...

Adaptive Estimation of Distribution Algorithms

open access: yes, 2008
Estimation of distribution algorithms (EDAs) are evolutionary methods that use probabilistic models instead of genetic operators to lead the search. Most of current proposals on EDAs do not incorporate adaptive techniques. Usually, the class of probabilistic model employed as well as the learning and sampling methods are static.
