Smoothed Analysis of the Komlós Conjecture

open access: yesCoRR, 2022
The well-known Komlós conjecture states that given $n$ vectors in $\mathbb{R}^d$ with Euclidean norm at most one, there always exists a $\pm 1$ coloring such that the $\ell_{\infty}$ norm of the signed-sum vector is a constant independent of $n$ and $d$. We prove this conjecture in a smoothed analysis setting where the vectors are perturbed by adding a

Upper and Lower Bounds on the Smoothed Complexity of the Simplex Method [PDF]

open access: yesTheoretiCS
The simplex method for linear programming is known to be highly efficient in practice, and understanding its performance from a theoretical perspective is an active research topic. The framework of smoothed analysis, first introduced by Spielman and Teng

The Smoothed Analysis of Algorithms

open access: yes, 2005
Spielman and Teng introduced the smoothed analysis of algorithms to provide a framework in which one could explain the success in practice of algorithms and heuristics that could not be understood through the traditional worst-case and average-case analyses. In this talk, we survey some of the smoothed analyses that have been performed.

Smoothed Analysis of the Simplex Method [PDF]

open access: yes, 2020
In this chapter, we give a technical overview of smoothed analyses of the shadow vertex simplex method for linear programming (LP). We first review the properties of the shadow vertex simplex method and its associated geometry. We begin the smoothed analysis discussion with an analysis of the successive shortest path algorithm for the minimum-cost ...

Smoothed analysis of probabilistic roadmaps

open access: yesComputational Geometry, 2007
The probabilistic roadmap algorithm that revolutionized robot planning is a simple heuristic that exhibits rapid performance with unbounded worst-case running time as a function of the input's combinatorial complexity. This paper initiates the use of smoothed analysis to explain the success of the probabilistic roadmap algorithm.

Cancer incidence in men: a cluster analysis of spatial patterns

open access: yesBMC Cancer, 2008
Background Spatial clustering of different diseases has received much less attention than single disease mapping. Besides chance or artifact, clustering of different cancers in a given area may depend on exposure to a shared risk factor or to multiple ...

A foreground extraction model on image multiscale decomposition

open access: yes四川大学学报. 自然科学版, 2021
In order to make up for the negative impact of texture on the extraction results of the traditional GrabCut model, this paper analyzes the scale characteristics of the image edge and color distribution, and combines the image multiscale decomposition and

Modelling stunting in LiST: the effect of applying smoothing to linear growth data

open access: yesBMC Public Health, 2017
Background The Lives Saved Tool (LiST) is a widely used resource for evidence-based decision-making regarding health program scale-up in low- and middle-income countries.

A New Smoothed Seismicity Approach to Include Aftershocks and Foreshocks in Spatial Earthquake Forecasting: Application to the Global Mw ≥ 5.5 Seismicity

open access: yesApplied Sciences, 2021
Seismicity-based earthquake forecasting models have been primarily studied and developed over the past twenty years. These models mainly rely on seismicity catalogs as their data source and provide forecasts in time, space, and magnitude in a ...
