1.Aiming at inefficiency of direct Monte Carlo method,viscoelastic finite element method was determined and Latin hypercube sampling(LHS) technique was used for random sampling so as to improve convergent velocity of calculation.针对直接Monte Carlo法效率较低的问题,在确定粘弹性有限元的基础上,采用拉丁超...
Latin hypercubemultiple minimaoptimizationpattern searchLatin Hypercube is a sampling technique forsearching n dimensional space. Like Monte Carlo methods, it retains random qualities, and yet Latin Hypercube is consistently more effective than Monte Carlo. Despite this fact, not a single paper has been...
aBased on the idea of ZMMM method, Latin Hypercube sampling technique according to the design variables is used to calculate sample points within the confidence value, and then the sample points are substituted into the finite element software to get the responses. 基于ZMMM方法想法,拉丁Hypercube...
In addition to providing a cost-effective and reliable sampling scheme, the Latin hypercube sampling technique also provides the user with the flexibility efficiently to study effects of distributional assumptions on key input variables without rerunning the computer model. 5 figures, 2 tables. 展开 ...
If you'd like to know more about the theory of Monte Carlo and Latin Hypercube sampling methods, please look at the technical appendices of the @RISK manual. See also: Confidence Intervals in @RISK How Many Iterations Do I Need? Last edited: 2023-02-10...
This paper analyzed the impact of the uncertainty of hydrogeological parameters and source/sink on the simulation results under the ideal groundwater flow conditions by using the Latin Hypercube Sampling(LHS).The Spearman partial(rank) correlation coefficient and the standard(rank) regression coefficient...

To tackle these issues, we introduce a Latin hypercube sampling initialization-based multi-strategy enhanced WOA (CAGWOA). It incorporates a COS sampling initialization strategy (COSI), an adaptive global search approach (GS), and an all-dimensional neighborhood mechanism (ADN). COSI leverages ...
Latin hypercube sampling (LHS) is a variance-reduction technique (VRT) that can be thought of as an extension of stratified sampling in higher dimensions. It can also be considered a generalization of antithetic variates, another VRT. This paper develops asymptotically valid confidence intervals for...
The latin hypercube sampling method, which represents the most efficient way to determine the statistics of the creep and shrinkage response of structures, has previously been developed and used under the assumption that the random param... Y Xi,ZP Ba?Ant - 《Probabilistic Engineering Mechanics》 ...
