Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In this study, various algorithms and optimization methods were employed to solve the inverse problem of magnetotelluric (MT) sounding, including Differential Evolution, Basin-Hopping, Dual Annealing, SHGO, Nelder-Mead, COBYLA, Newton-CG, Newton-Raphson, and Hooke-Jeeves methods. These approaches were applied to identify and optimize both the global and local minima of the objective function, which quantifies the best fit between observed and theoretical MT data. By achieving an optimal agreement between measured and modeled datasets, these methods ensured high accuracy and reliability in the solution of the MT inverse problem.
