On Optimizing the Arithmetic Precision of MCMC Algorithms [PDF]

open access: yes2013 IEEE 21st Annual International Symposium on Field-Programmable Custom Computing Machines, 2013
Markov Chain Monte Carlo (MCMC) is an ubiquitous stochastic method, used to draw random samples from arbitrary probability distributions, such as the ones encountered in Bayesian inference. MCMC often requires forbiddingly long runtimes to give a representative sample in problems with high dimensions and large-scale data. Field-Programmable Gate Arrays

A Novel Evolutionary Arithmetic Optimization Algorithm for Multilevel Thresholding Segmentation of COVID-19 CT Images

open access: yesProcesses, 2021
One of the most crucial aspects of image segmentation is multilevel thresholding. However, multilevel thresholding becomes increasingly more computationally complex as the number of thresholds grows. In order to address this defect, this paper proposes a

A Multi-Strategy Improved Arithmetic Optimization Algorithm

open access: yesSymmetry, 2022
To improve the performance of the arithmetic optimization algorithm (AOA) and solve problems in the AOA, a novel improved AOA using a multi-strategy approach is proposed. Firstly, circle chaotic mapping is used to increase the diversity of the population. Secondly, a math optimizer accelerated (MOA) function optimized by means of a composite cycloid is

Formal Proofs for Nonlinear Optimization [PDF]

open access: yes, 2015
We present a formally verified global optimization framework. Given a semialgebraic or transcendental function $f$ and a compact semialgebraic domain $K$, we use the nonlinear maxplus template approximation algorithm to provide a certified lower bound of

Convex Combinatorial Optimization [PDF]

open access: yes, 2003
We introduce the convex combinatorial optimization problem, a far reaching generalization of the standard linear combinatorial optimization problem. We show that it is strongly polynomial time solvable over any edge-guaranteed family, and discuss several
