Interpolation and scattered data fitting on manifolds using projected Powell–Sabin splines [PDF]
, 2008 We present methods for either interpolating data or for fitting scattered data on a two-dimensional smooth manifold. The methods are based on a local bivariate Powell-Sabin interpolation scheme, and make use of a family of charts {(Uξ , ξ)}ξ∈ satisfying ...

Validity of the Quadratic Fitness Function [PDF]
Nature New Biology, 1973 MANLY1 has questioned whether the quadratic fitness function can be applied in general to the measurement of selection for quantitative characters. As he points out, if individuals survive with a probability w per day, then after t days the probability of survival is wt.

Fitting a function to time-dependent ensemble averaged data
Scientific Reports, 2018 Time-dependent ensemble averages, i.e., trajectory-based averages of some observable, are of importance in many fields of science. A crucial objective when interpreting such data is to fit these averages (for instance, squared displacements) with a ...

The choice of equivalent dose fitting function in ESR dating of old fossil samples
He jishuBackgroundIn electron spin resonance dating (ESR) of old fossils, the double saturation exponential (DSE) function is often used for the equivalent dose (DE) determination, it generally requires more than 15 dose points and the maximum irradiation dose ...

Variation function fitting method based on particle swarm optimization
MATEC Web of Conferences, 2016 In the Kriging interpolation method, different theory models of variation function are selected and fitted. There are many common variation function models, such as spherical model, index model, Gaussian model and so on.

OneMax Is Not the Easiest Function for Fitness Improvements
Evolutionary Computation, 2023 Abstract We study the (1:s+1) success rule for controlling the population size of the (1,λ)-EA. It was shown by Hevia Fajardo and Sudholt that this parameter control mechanism can run into problems for large s if the fitness landscape is too easy.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

A Genetic Programming-Driven Data Fitting Method
IEEE Access, 2020 Data fitting is the process of constructing a curve, or a set of mathematical functions, that has the best fit to a series of data points. Different with constructing a fitting model from same type of function, such as the polynomial model, we notice ...
