Abstract

In this article, there are mainly presented two methods for the optimization of some functions of interpolation. A first method is that of minimizing functional operators, thus drawing conclusions on the importance of knots where the measurements are made, therefore allowing the number of knots to be reduced. A second method is that of genetic algorithms which is used to optimize an objective function, starting from a population of codifications of possible solutions for the problem, and where probabilistic transition rules are used instead of determinist ones.
