Assessing the 2D models of geotechnical variables in a block of a Cuban lateritic site. Fifth part: combinatorial optimization of the UPD method

Abstract

In the work, through exhaustive searches, we study the combinatorial optimization of two - dimensional UPD modeling of the variables: thickness and concentrations of nickel, iron and cobalt in a block of a Cuban lateritic deposit. The UPD method is a numerical estimator with parameters q, δ and ε that from a set of data allows to obtain a mesh model that represents the behavior of a property U of some natural or technological object that is investigated in a certain spatial domain. For a set of n points (Pi; Ui), which express the values Ui for the corresponding spatial coordinates Pi, this method allows to estimate the value of U for any coordinate P of its domain, as a linear combination of powers q of euclidian distances.
